Navigating PowerPoint presentations with ease is essential, especially when capturing the attention of your audience. One tool that’s often overlooked but incredibly effective is the laser pointer feature. Transforming your cursor into a laser pointer can significantly enhance your presentation by directing focus and adding a professional touch.

We can invoke this handy feature with a few simple steps. As we advance through our slides, all we need is to press and hold the Ctrl key while clicking and dragging the left mouse button. This converts our cursor into a bright, engaging laser pointer, ensuring our audience stays glued to vital points on each slide.

Imagine the difference it makes when discussing complex graphs or intricate data. Instead of waving our hands or using cumbersome external pointers, the built-in laser pointer streamlines our presentation. It helps us maintain a seamless flow and keeps our audience’s attention firmly fixed where it’s needed most.

JUMP TO TOPIC

Choosing the Right Background Color

Utilizing templates for a professional look, setting up slide show and transition options, highlighting key points using pointer options, incorporating multimedia and narrations, facilitating smooth presentations with shortcut keys, selecting the appropriate laser pointer color, converting mouse pointer into a virtual laser pen, setting up automatic slide advancements, troubleshooting hardware and software issues, optimizing powerpoint slide setup.

Crafting an engaging PowerPoint presentation involves careful consideration of the slide setup, such as background color, use of templates, and slide show configurations.

Selecting the perfect background color is crucial. We need to ensure that the text is readable and visually appealing to the audience. A neutral color like white or light gray can work wonders for readability.

Dark backgrounds can create a striking contrast with white text, but they can be hard on the eyes if overused. Aim for a balance that supports the content without overwhelming it. We should also think about the setting where the presentation will be shown. Different lights can affect how colors appear on the screen.

Using templates can greatly enhance the professionalism of our presentation. PowerPoint offers a variety of built-in templates that are designed for clean and consistent visuals. These templates ensure that our slides maintain a cohesive look, which is essential for keeping the audience engaged.

By customizing these templates, we can match our brand colors or the theme of our presentation. It’s a quick and efficient way to prepare slides without starting from scratch. Remember, a professional look isn’t just about aesthetics; it’s about making sure the audience can easily follow our content.

Slide show settings and transitions can make or break the flow of our presentation. In the “Set Up Slide Show” menu, we can choose how our slides advance, whether it’s manually or automatically. Automatic slides can be useful for timed presentations while manual control gives us flexibility during talks.

Transitions between slides should be smooth and not too flashy. Simple transitions like “Fade” or “Wipe” can maintain a professional appearance without distracting the audience. It’s also essential to test our slide show mode to confirm that everything runs smoothly before the actual presentation.

Engaging Your Audience with Effective Presentation Features

Effectively engaging an audience involves using presentation features like highlighting key points, incorporating multimedia, and leveraging shortcut keys for smooth transitions. These tools help maintain audience focus and enhance the overall impact of your presentation.

Emphasizing key points during a PowerPoint presentation is crucial. By utilizing the laser pointer feature, we can direct attention to specific areas on the slide.

To activate the laser pointer, press the Ctrl key (Windows) or Command key (Mac) while holding down the left mouse button. This turns your cursor into a laser pointer, allowing you to highlight important parts of your slide without breaking engagement.

Using Pointer Options , we can also switch to different types like the pen or highlighter. These options are accessible by right-clicking the slide and navigating to Pointer Options . Each option has its unique way of maintaining audience attention and ensuring clarity.

Multimedia elements like videos, audio clips, and sound effects can make a presentation more engaging. They break the monotony of text and add dynamic components to the slides.

Including narrations is especially effective when presenting remotely. We can record narrations by going to the Slide Show tab and selecting Record Slide Show . This allows us to add commentary and explanations that play with the slides, making the presentation more personable and immersive.

Additionally, embedding videos and sound clips relevant to the content can aid in illustrating complex ideas. Just ensure these elements are well-integrated and don’t overpower the main message.

Smooth transitions and professional flow are essential for a captivating presentation. Knowing keyboard shortcuts can help manage this with grace.

Starting the slide show can be done quickly by pressing F5 . To pause or resume narration, we can use the Ctrl + P and Ctrl + L for a laser pointer. These shortcuts save time and keep the presentation seamless.

Using the Ctrl key or Command key combined with other keys allows for efficient navigation. Ensuring we are familiar with these shortcuts enhances our ability to engage the audience effectively, focusing on content delivery rather than technical issues.

Employing these presentation features can significantly improve audience engagement. By incorporating visual aids, narrations, and efficient navigation, we create a more interactive and dynamic experience.

Mastering Laser Pointers for Audience Focus

To master laser pointers in PowerPoint, it’s crucial to focus on choosing the right color and converting your mouse pointer into a virtual laser pen.

Choosing the right laser pointer color can make a world of difference in keeping the attention of the audience. Standard pointer colors include red, green, and blue.

Red lasers are the default and most common, easily visible against most backgrounds.

Green lasers are more powerful and visible, especially in brightly lit rooms or on complex slides. This can aid in drawing attention more effectively .

Blue lasers are less common but can add a unique touch to your presentation. They stand out uniquely against white and light-colored backgrounds, potentially capturing more interest.

Given our audience, we recommend testing the laser pointer on your slides beforehand. This can help ensure maximum visibility and impact.

Turning your mouse cursor into a laser pointer in PowerPoint is straightforward and enhances the professionalism of your presentation.

Start your Slide Show by pressing F5 or Shift+F5 . To activate the laser pointer, right-click on the slide.

Go to Pointer Options and select Laser Pointer . You can hold the Ctrl key and drag the left mouse button to use it as a laser pointer during your presentation.

These simple steps can transform your mundane mouse pointer into a dynamic tool for pointing out key details on your slides, keeping the audience more engaged. Pay attention to how you use this tool, ensuring smooth movements to maintain a professional demeanor.

Technical Preparation for Self-Running Presentations

Setting up self-running presentations in PowerPoint requires detailed planning and understanding of key functionalities. Our focus spans from configuring slide advancements to handling potential technical issues.

Setting up automatic slide advancements is crucial for a self-running presentation.

In Microsoft PowerPoint , this can be accomplished by using the “Slide Show” menu. We need to:

• Navigate to the “Transitions” tab.
• In the “Timing” group, uncheck the “On Mouse Click” option.
• Check the “After” box and set the time duration for which each slide remains on screen.

For more control, use Slide Show View and Reading View to preview and tweak timings.

To automate media, we can embed videos and set them to play automatically. If using a Mac, ensure compatibility by using standard formats like MP4.

Preparation involves anticipating and solving hardware and software issues.

Testing the presentation on the actual equipment helps us identify and fix issues beforehand. Make sure the display settings align with the presentation requirements.

For hardware:

• Check all connections (HDMI, VGA).
• Ensure the projector resolution matches the presentation.
• Carry backup cables and adapters.

For software:

• Update PowerPoint to the latest version.
• Test presentation on different OS versions .
• Use training courses to stay updated on features and potential troubleshooting techniques.

If a technical issue arises during the presentation, quick actions such as using the pause and resume functions can help maintain flow. Keeping a backup on a USB stick or cloud ensures we can quickly switch to another device if needed.

Setting up Your Slideshow in PowerPoint

To ensure your PowerPoint presentation runs smoothly, it’s essential to set up your slideshow view, customize presentation settings, and configure it to self-run if needed.

Initiating Slide Show View

Starting your slideshow is the first step to showcasing your presentation. I hit F5 to enter Slide Show view quickly. Alternatively, I navigate to the Slide Show tab and click either From Beginning or From Current Slide . Using these methods gives me control over starting points based on where I left off in my preparation.

Another handy approach is to use the Reading View for a more intimate look at the slides with navigational ease. By going to the View tab, I can switch to this mode, which mimics the final presentation experience but with more flexibility. This variety in starting options ensures I can adapt to different presentation contexts effortlessly.

Customizing Presentation Settings

PowerPoint offers a plethora of settings to tailor the presentation experience. I always explore the Set Up Slide Show dialog, accessible via the Slide Show tab. Here, I adjust options like setting the presentation to loop continuously or pausing after each slide for audience interactions.

I also make sure to adjust the Show Options for high-contrast settings if I’ll be presenting in a well-lit room. This involves tweaking the Background and visual contrast to ensure all text and images are visible.

Another feature is enabling narrations and laser pointer recordings. This is perfect for when I need to rehearse with full audio-visual aids or share the presentation with remote audiences.

Self-Running Slide Show Setup

Sometimes, I need my presentation to run automatically. This is particularly useful for kiosks or unattended displays. By going to the Set Up Show dialog, I choose the Browsed at a kiosk option. Then, I fine-tune the slides’ advance timing in the Transitions tab.

Setting a precise timing for each slide ensures smooth transitions and keeps the audience engaged without my intervention. I also add animation and transition effects where necessary, but sparingly to avoid overwhelming the viewers.

Lastly, enabling rehearse timings helps me practice the flow, ensuring all aspects are clocked to perfection before the final show.

Starting your slideshow is the first step to showcasing your presentation. I hit F5 to enter Slide Show view quickly. Alternatively, I navigate to the Slide Show tab and click either From Beginning or From Current Slide. Using these methods gives me control over starting points based on where I left off in my preparation.

Setting precise timing for each slide ensures smooth transitions and keeps the audience engaged without my intervention. I also add animation and transition effects where necessary, but sparingly to avoid overwhelming the viewers.

Navigating Slides Like a Pro

Navigating slides efficiently is crucial for delivering a seamless and engaging presentation. Mastering keyboard shortcuts and utilizing the Slide Sorter View can significantly enhance your control.

Using Keyboard Shortcuts

Keyboard shortcuts are a presenter’s best friend. Pressing F5 starts the Slide Show from the beginning, while Shift+F5 begins it from the current slide. When presenting, press the Ctrl key and drag the left mouse button to use the laser pointer.

Here are some essential shortcuts for navigation:

• N or Spacebar: Move to the next slide.
• P or Backspace: Return to the previous slide.
• B: Display a black screen. Press B again to resume.
• W: Display a white screen. Press W again to resume.

Keyboard shortcuts can also manage timings. Pressing T displays the elapsed time, and pressing Ctrl+T allows you to reset timings. Using these shortcuts keeps your presentation smooth and professional.

Leveraging Slide Sorter View

Slide Sorter View offers a bird’s-eye view of your entire presentation. Access it by clicking the Slide Sorter button on the View tab. This mode shows thumbnails of each slide, making it easy to rearrange them by dragging and dropping.

This view is perfect for preparing complex presentations. You get a clear picture of the flow and can quickly spot any slide out of place. Adjustments are intuitive.

If you need to hide a slide temporarily, right-click on it and choose “Hide Slide.” This is useful for tailoring presentations to different audiences. Leveraging Slide Sorter View ensures your presentation is organized and impactful.

Enhancing Your Presentation with Laser Pointers

Using a laser pointer can significantly improve your PowerPoint presentations by highlighting key points and maintaining audience engagement. For the best results, choose an appropriate laser pointer color and practice effective virtual laser pen techniques.

Choosing the Right Laser Pointer Color

The color of your laser pointer can make a big difference. Red laser pointers are the most common and are excellent for indoor settings. They work well in low-light environments but may struggle in brightly lit rooms.

For brighter rooms, green lasers have better contrast and higher visibility. They are more effective at capturing attention, especially on large screens. Blue lasers, though less common, offer a modern touch, making them suitable for unique presentation settings.

Virtual Laser Pen Techniques

When presenting virtually, leveraging the built-in laser pointer in PowerPoint can be game-changing. Here’s how I do it.

First, start your slide show by pressing F5 . To switch to the laser pointer, right-click on the slide, navigate to Pointer Options , and select Laser Pointer . To maintain fluid movements, press and hold the Ctrl key while clicking and dragging the mouse.

For maximum effectiveness:

• Practice smooth and steady movements.
• Avoid jerky motions to keep your audience focused.
• Use it sparingly to emphasize key points without distraction.

Using these techniques, you can draw attention precisely where needed, enhancing the clarity and impact of your presentation.

Engaging Your Audience Effectively

To truly captivate your audience during a PowerPoint presentation, leverage interactive slide elements and foster a dynamic Q&A environment. Use these techniques to keep your listeners attentive and involved throughout.

Interactive Slide Elements

Interactive slide elements can make a significant impact on engagement. Hyperlinks , embedded videos , and animated objects can trigger involvement and focus attention. For example, embedding a short, relevant video to illustrate a point can be much more effective than text alone.

Using the laser pointer tool as a highlighter is also crucial. By pointing out specific text or images, you emphasize important details.

Interactive Slide Tips:

• Use animation sparingly to highlight key points.
• Include clickable elements for audience-led navigation.
• Incorporate audio cues for transitions.

By making your content interactive, you create a dynamic flow that keeps the audience mentally alert. Mixing these tools ensures that your presentation remains lively and engaging.

Asking and Answering Questions

Encouraging questions during your presentation is paramount. I start by outlining to the audience that their input is valued. This signals openness and sets the tone for active participation.

Posing questions to the audience serves dual purposes: it stimulates thought and provides immediate feedback. For instance, asking, “How do you currently approach this task?” invites personal reflection and can lead to diverse discussions.

When answering questions, I use the laser pointer to focus on relevant slide sections or data points. This keeps the audience visually connected to the topic.

Express gratitude for each question and provide clear, concise responses. This approach fosters a community atmosphere where everyone’s insights seem valued, enhancing their overall engagement.

The 7 Best PowerPoint Clickers on the Market (2024 Review)

Want to step up your presentation game? A smart and reliable PowerPoint clicker is all you need🎯

It is a small wireless remote that fits in your hand. Use it to move between different slides. Pause or restart, laser point, and control what your audience gets to see.

The right PowerPoint clicker can turn you into a presentation wizard🧙🏼‍♂️

But with so many of them on the market, how do you find the right one? Below, I’ve listed the seven absolute best PowerPoint clickers on the market.

⚠️Spoiler Alert⚠️

My top pick is the Logitech R800 .

It stands out as one of the most advanced clickers with very well-thought-out features. Such as a small LCD to help you track the time gone into presenting. Set a timer on it or monitor the battery level of your clicker🔋

However, these might not make the most important features for your needs. To find the best of the best for yourself, continue reading.

A quick note of how we test each clicker

Each clicker on this list is best in at least one crucial aspect. Be it the battery or the laser light, or something else.

To pull this list together, we have evaluated each presenter on a total of 5 parameters 💪

• Laser Pointer
• Control Range
• Compatibility
• User Friendliness

So, in the review below, we will score each of these parameters for every clicker. Based on these, you can find the clicker that best suits your needs.

PowerPoint Clickers Reviewed

1: Logitech R800 (Best Overall)

2: Kensington Wireless Presenter K33272WW (Best Basic)

3: Kensington K72426AMA (Best Cursor Control)

4: Logitech R500 (Easiest to Use)

5: Amerteer Wireless Presenter (Best on Budget)

6: Amerteer Finger Ring Presenter (Best Ring Presenter)

7: NINJAABXY Wireless Clicker (Best Ergonomic Design)

This list was last updated on July 2nd, 2024.

1. Logitech R800 (Best Overall)

The Logitech R800 is the perfect choice for professionals who can’t stand anything less than perfection.

The best highlight of this presenter? An excellent battery life. It works on two AAA batteries that will give you a 20-hour lifetime in laser light mode😍

And in simple presentation mode, the battery life goes up to 1050 hours. No meeting lasts longer than that.

Plus, the LCD screen allows users to track the battery life. So you are well informed about the battery life, and there’s no guessing game.

Specifications in the version we reviewed

• Laser Light: Green laser light
• Connectivity: Plug-and-play USB Receiver
• Battery: 2 AAA batteries
• Control Range: 100 Feet (30 meters)
• Special feature: LCD Display with track of time and battery

Score on review parameters

• Laser Pointer: Green laser light is a big plus as it never fails (not even in well-lit rooms).
• Battery Type: Two replaceable AAA batteries give you an excellent battery life of 20 to 1050 hours.
• Control Range: A 100-feet control range. This means you can roam around your conference room (and even in a nearby garden) freely. The clicker will still work. And if you get a little too away, the reception indicator will beep to bring you back in the control range.
• User Friendliness: Plug and play means just connecting the USB receiver to any Windows PC, and that’s it. No complicated setups. When done, unplug the USB receiver and store it inside the actual clicker.
• LCD Screen: Here’s an additional feature that we would love to highlight. The LCD on top of the presenter allows you to track the time, the battery, and wireless reception. Get silent or vibration alerts when the battery goes low.
• Value-for-Money: For $78 and all these modern features, we won’t call it exorbitant. But yes, slightly overpriced.

Overall Spreadsheeto Rating: 💚💚💚💚💚💚 (6/6)

This, in my view, is the best choice for professionals. With live information on the LCD screen, there’s no chance of running out of battery or range.

2. Kensington Wireless Presenter K33272WW (Best Basic)

If you need a basic PowerPoint clicker that’s reliable and easy to use, look no further. This wireless presenter from Kensington will take care of it all.

With a four-intuitive-button design, it is very user-friendly. You need not wrap your head around a complicated design with lots of buttons and unnecessary functions😏

It’s simple, very durable, and ergonomically built to fit your hands.

It offers AES 28-bit encryption (also adopted by the US Govt. as the encryption standard). This makes it safe and secure against any hacking attempts.

• Laser Light: Red       
• Battery : External battery
• Control Range: 65 Feet
• Special feature: AES 128-bit encryption (secure wireless technology)
• Price : $38
• Laser Pointer: A red pointer laser light is great for a basic presenter.
• Battery Type: Replaceable battery goes a long way.
• Control Range: A Plug-and-play 2.4GHz and 65 feet control range are pretty good even if you have a large-sized auditorium to address.
• User Friendliness: An intuitive design of four buttons to move between slides, hide the screen and use the laser light makes it very user-friendly.
• Value-for-Money: If you’re focused on reliability and longevity – a basic design for $38 might bring great value for you. But considering the only very basic features offered by it, we don’t score it great in this aspect.

Overall Spreadsheeto Rating: 💚💚💚💚💚🤍 (5/6)

Although the Kensington K33272WW provides an internal compartment for storing the USB receiver, it’s inside the battery cover. You might find it difficult to detach the battery cover to store the USB receiver every time. Other clicker models have a more convenient style for USB receiver storage.

3. Kensington K72426AMA (Best Cursor Control)

Which is the second best PowerPoint clicker on this list? The Kensington K72426AMA.

Why? The list of reasons is a little long✌

But the best part is the joystick in it that gives you cursor control. This PowerPoint clicker from Kensington is almost a portable mouse.

Other clickers would allow you to move between slides, but what if you want to click something on the slide (like a hyperlink)? Would you rush back to your PC to use the mouse? That’s no longer needed.

Use this clicker to launch any file or click anywhere with its joystick.

Wireless presenter with bright green laser pointer and cursor control for presentations.

• Laser Light: Green laser
• Connectivity : Plug-and-play USB / MicroSD Card
• Control Range: 150 Feet (50 meters)
• Compatibility : Windows & Mac OS X (Keynote and PowerPoint)
• Special feature: Cursor control mode (Joystick helps using it as a mouse)
• Price : $45
• Laser Pointer: Green laser light which is 10X brighter than ordinary red laser pointers. Also, if you think red is a little too harsh to use on-screen, go green.
• Battery Type: Replaceable battery.
• Control Range: Excellent control range of 150 feet. That’s the best control range we have seen in all the presenters reviewed until now.
• User Friendliness: Simple design with four intuitive buttons. Specially designed contours to facilitate holding for long hours.
• Value-for-Money: Excellent features for a reasonable price of $45. Great value for money.

Kensington offers similar models in two opalescent colors – pearl white and rose gold. Both of them are real eye candies. If you want an aesthetic look with great functionality, check out Kensington K75771WW (Pearl White) and K757720WW (Rose Gold).

4. Logitech R500 (Easiest to Use)

Minimalism, but with some sass! If that’s your demand, the Logitech R500 is meant for you.

The R500 is a hassle-free, reliable presenter. It comes with three big buttons that are intuitively designed so you can confidently navigate between slides without having to look down⚡

Affordable, easy-to-use wireless presenter with laser pointer and presentation mode.

• Connectivity : If you’re buying R500, must take note of this feature. Unlike all other clickers, the R500 can also be connected via a Bluetooth connection in addition to a USB receiver.
• Value-for-Money: R500 offers great features but, for $76, it’s a little over-priced.

If you want to navigate confidently, easily, and freely between slides of your daily presentations – I believe R500 to be one of the best fits for you. It is compatible with almost all operating systems.

5. Amerteer Wireless Presenter (Best on Budget)

Got hyperlinks in your slides that you want to launch during the presentation?

Ordinary presenters won’t help you with this situation – you need the Amerteer Wireless Presenter . It’s slim like a pen and lightweight like a feather🖊

If you need an excellent presenter but are on a tight budget – you’ll not find an option better than this.

• Connectivity : Plug-and-play USB Receiver
• Battery : AAA battery
• Special feature: Supports hyperlinks
• Control Range: 39 Feet (12 meters)

Laser Principle Eman Ali Ateeq

: objectives • Introduction • Properties of laser light • Lasing process • Optical cavity and laser modes • Types of lasers • Lasers applications

Introduction Laser technology is one of the most rapidly developing areas in modern technology. When the laser was invented, in 1960, it was classified as a solution in search of aproblem , and today laser technology is applied in many different areas such as: medicine, communication, daily use, military, and industry

In principle, the laser is a device which transforms energy from other forms into electromagnetic radiation. From this light output, the laser got part of its name: LASER = Light Amplification by Stimulated Emission of Radiation. The energy put into the laser can be in any form such as: electromagnetic radiation, electrical energy, chemical energy, etc.

Properties of Laser Radiation • Monochromaticity : Identical wavelengths (one wavelength ) • Directionality : Identical directions in space : angular spreading of a laser beam is very small , and described by a small divergence angle (of the order of milli-radians). • Coherence : Identical phase

Lasing process • Possible Processes Between Photons and Atoms • Photon Absorption: A photon with frequency n12 hits an atom at rest, and excites it to higher energy level (E2) while the photon is absorbed.

Spontaneous emission of a photon: An atom in an excited state emits a photon with frequency n12 and goes to a lower energy level (E1).

Stimulated emission of a photon: A photon with frequency n12 hit an excited atom and cause emission of two photons with frequency n12 while the atom goes to a lower energy level (E1).

Thermodynamic (Thermal) Equilibrium • From thermodynamics we know that a collection of atoms, at a temperature T[0K], in thermodynamic equilibrium with its surrounding, is distributed so that at each energy level there is on the average a certain number of atoms. • The Boltzmann equation determines the relation between the population number of a specific energy level and the temperature: • 1. The higher temperature, has higher population number. • 2. The higher the energy level, has lower population number.

Ni = A * exp (-Ei/kT) • Ni = Population Number = number of atoms per unit volume at certain energy level Ei. • k  = Boltzmann constant:  k = 1.38*1023 [Joule/0K]. • Ei = Energy of level i. • A = proportionality constant. • T = Temperature in Kelvin[0K]

Population Inversion • At least one of the higher energy levels has more atoms than a lower energy level.

Atoms stay in an excited level only for a short time (about 10-8 [sec]), and then they return to a lower energy level by spontaneous emission. • When the transition probability is low for a specific transition, the lifetime of this energy level is longer (about 10-3 [sec]), and this level becomes a "meta-stable" level. In this meta-stable level a large population of atoms can assembled. this level can be a candidate for lasing process

If a population inversion exists between two energy levels, the probability is high that an incoming photon will stimulate an excited atom to return to a lower state, while emitting another photon of light. The probability for this process depend on the match between the energy of the incoming photon and the energy difference between these two levels

As a result of the stimulated emission process, we have two identical photons created from one photon and one excited state. The amplification is made that the number of photons has increased.

Three Level Laser • Atoms are pumped from the ground state (E1) to energy level E3, and decay to the meta-stable energy level E2. • Since the lifetime of the meta-stable energy level (E2) is relatively long, many atoms remain in this level. • If the pumping is strong enough, then after pumping more than 50% of the atoms will be in energy level E2, a population inversion exists, and lasing can occur.

Four Level Laser

advantage of the four level laser • low population of the lower laser energy level (E2). To create population inversion, there is no need to pump more than 50% of the atoms to the upper laser level. The population of the lower laser level (N2(t)) is decaying rapidly to the ground state, so practically it is empty. Thus, a continuous operation of the four level laser is possible even if 99% of the atoms remain in the ground state

The lasing threshold of a four level laser is lower. • The efficiency is higher. Required pumping rate is lower. • Continuous operation is possible

Optical Cavity and laser Modes • Laser Cavity is made of mirrors at the end of the active medium. These mirrors reflect the electromagnetic radiation back to the cavity again and again, to create the standing waves. • The active medium is a collection of atoms or molecules, which can be excited into a population inversion situation, and can have electromagnetic radiation extracted out of it by stimulated emission. • solid, liquid, gas or plasma. • determines the possible wavelengths that can be emitted from the laser

The excitation mechanism • the source of energy that raises the atoms in the active medium into their excited state, to creating population inversion. • Optical pumping : Excitation by photons Flash lamps Another laser

Electrical excitation of a gas When the high electrical voltage is applied, electrons are released from the cathode and accelerated toward the anode. On their way, these electrons collide with the gas molecules and transfer energy to them. the gas molecules are raised to excited state.

Chemical Excitation energy is supplied by the chemical reaction between two atoms or molecules • Collisions with atoms This is the standard excitation mechanism in the commercial gas lasers such as: He-Ne laser, or CO2 laser. In this method at least two gasses are inside the laser tube. One gas receives the energy from the collision with the accelerated free electrons. The second gas receives energy from collisions with the excited molecules of the first gas.

Feedback Mechanism • returns part of the coherent laser radiation which was created inside the active medium using mirrors at both ends of the active medium so that the radiation is moving back and forth between them. • Usually one mirror is 100% reflecting The other mirror is partially reflecting (10%-99%), according to the laser type.

The part of the radiation which is not reflected back into the optical cavity, is transmitted out, and it is the laser output. • The feedback allows each photon to pass many times through the active medium, so enough amplification will result. • Because of the feedback mechanism, only photons which move between the mirrors remain in the active medium, which give the directionality of the output beam.

Laser Gain • Active medium gain depends on: a)Population Inversion b) Fluorescence line-shape of the spontaneous emission that is related to the lasing transition • 2. Losses in the laser, which include: a) Reflections from end mirrors. b) Radiation losses inside the active medium - due to absorption and scattering. c) Diffraction losses ; due to the finite size of the laser components.

Loop Gain (GL) • E1 = Intensity of radiation at the beginning of the loop. • E5= Intensity of radiation at the end of the loop.

GL = E5/E1 = R1* R2*GA2 *M R1,R2 = Reflection coefficients of the laser mirrors. GA = Active medium gain as a result stimulated emission. GA = exp(+bL) b = Gain coefficient. L = Active Medium length. M = Optical Loss Factor in a round trip path in the laser cavity. M = exp(-2aL) a = Loss coefficient. GL = R1* R2* exp(2(b-a)L)

When (GL > 1), the beam intensity will increase after one return pass through the laser. • When (GL < 1), the beam intensity will decrease after one return pass through the laser. laser oscillation decay, and no beam will be emitted. • For continuous laser , the threshold condition is: • (GL)th = 1 = R1 R2 GA2M = R1* R2* exp(2(b-a)L)

Longitudinal Modes in a Laser • Longitudinal Mode - Intensity distribution measured along the optical axis of the laser. • are standing waves along the optical axis of the laser. • The allowed frequencies inside an optical cavity are determined by the length of the cavity (L) and the index of refraction of the active medium. Only those frequencies which create nodes at both mirrors are allowed. , the cavity length must be an integer multiplication of half their wavelengths.

Only those frequencies (modes) that have amplification above certain minimum lasing threshold, will be emitted out of the laser.

Transverse Mode : Intensity distribution measured over beam cross section perpendicular to the optical axis of the laser. • created by the width of the cavity, which enables a few modes to develop inside the laser cavity.

Electric Field Distribution of TEM modes • Radiation intensity of the laser beam is a measure of the square of the electric field of the electromagnetic radiation.

Laser types Laser types differ from each other by : • The state of matter of the active medium: solid, liquid, gas, or plasma. • The spectral range of the laser wavelength: visible spectrum, Infra-Red (IR) spectrum, etc. • The excitation (pumping) method of the active medium: Optic pumping, Electric pumping, etc. • The characteristics of the radiation emitted from the laser. • The number of energy levels which participate in the lasing process. But the active medium state control the other cretrei
