Did you know that PowerPoint includes a free (hidden) laser pointer option that you can use without having to buy one? Even if you have a differetn pointer you like to use, this built in pointer is a great backup whenever you need it. It also comes in three colors too (red, green, and blue).

Take your PPT skills to the next level

Why is a pointer useful during a powerpoint presentation.

A laser pointer is useful for highlighting or pointing out exactly what you want your audience to focus during your presentation. In other words, instead of trying to verbally tell somewhere where to look on your slide, you use your pointer to point it out.

For example, if you want to bring attention to the 100% year-on-year growth on your slide, you can simply use PowerPoint’s laser pointer to point it out on your slide.

The more content you have on your slide, the more useful it is to point out what you are talking about with your laser pointer.

In the same way, you could use it to highlight:

• Different rows in a table
• The different people on your team (as you talk about them)
• Ideas for a marketing campaign as you highlight them

In short, a laser pointer allows you to better control the ebb and flow of your presentation, by pointing things out on screen while you talk about them.

While there are probably a million different laser pointers you can use, the one I use most is the hidden laser pointer in PowerPoint. Read on to see how to use it.

How to change your cursor into a laser pointer

There are two different ways to turn your cursor into a laser pointer in PowerPoint. The first is using your mouse, the second is the laser pointer shortcut. Let’s start with your mouse first.

The advantage of this first technique is it locks the laser pointer, so you don’t have to hold any keys down on your computer. On top of that, once you turn it on using your mouse like this, the laser pointer remains on as you advance through your presentation. So you don’t have to turn it on for every slide.

To turn your mouse cursor into a laser pointer during your PowerPoint presentation, simply:

• Hit F5 to start your Slide Show ( see my guide here for other slide show shortcuts )
• Right-click your slide
• Open the Pointer Options
• Select Laser pointer

Doing so, your mouse cursor becomes a colored pointer that you can drag around on your screen to highlight things in your presentation as pictured below. 

NOTE: You cannot change the color of the pointer while giving a presentation. If you want a different color, you need to change its color before you run your presentation

Turning off the laser pointer

There are two ways to turn the laser pointer off in PowerPoint. The first is simply to hit the Esc key on your keyboard. Hitting Esc, the laser pointer reverts back to the normal mouse cursor.

An alternative way to turn the laser pointer off, is simply to change it into something else. You can do that as follows:

• Right-click your slide in Slide Show view
• Select Pointer Options
• Select Arrow Options (or choose Pen or Highlighter)
• Select Visible

Selecting  Visible  turns your mouse cursor back into the normal PowerPoint arrow cursor.

Laser pointer shortcuts

My favorite way to use the laser pen is simply to use its shortcut. That’s becuase using shortcuts make everything easier in PowerPoint AND saves you a ton of time.

NOTE: If you want to learn all the best PowerPoint shortcuts and tricks, they are all inside our PowerPoint Pro Membership here .

To use this shortcut, simply hold the Ctrl key on your keyboard, then click and drag with your mouse. Doing so turns your cursor into the laser pointer color you have selected (red is the default). 

When you are done, simply let go of the Ctrl key and the pointer disappears. This is a fast and easy way to highlight things in your presentation on the fly and impress your clients and colleagues.

I personally find this to be the fastest way to turn the laser pointer on and off. In the picture below, you can see what the blue laser pointer looks like in PowerPoint.

You can alternatively lock the laser pointer by hitting Ctrl + L on your keyboard. This locks the laser pointer, so you don’t have to hold down anything on your keyboard (like with the previous shortcut). 

To unlock the pointer when you are done with it, simply hit the Esc key to return to the normal mouse cursor.

How to change the laser pointer color

PowerPoint has three different laser pointer colors you can choose from in PowerPoint. Red is the default color, but you can easily change its color to green or blue.

By default, the the PowerPoint pointer is red, but you can easily it to green or blue if you want to, through the Set Up Slide Show  dialog box.

Just be aware that you need to set the color before you run your presentation.

• Click the  Slide Show  tab
• Select the  Set Up Slide Show  command
• Open the  Laser Pointer Color  options
• Choose a color (red, green, or blue)

QUESTION: Does changing the laser pointer color change it’s color for all my presentations?

The color you choose for your pointer is saved in the PowerPoint presentation you changed it for. It is not set as the new default color for all your PowerPoint presentations. So, feel free to change your pointer color to best match the template / presentation you are working with.

By default, PowerPoint always starts with a red laser pointer. So unless you need a color other than red, you do not need to worry about changing it.

Does the pointer work when presenting two presentations at the same time?

The answer is yes (as you can see pictured above).

For example, if you are running an English and Chinese version version of your presentation at the same time for two different audiences (which is what we did all the time when I was living in China), the laser pointer still works in each presentation.

The catch is, you need to use the laser pointer shortcut (discussed above), and make sure you click into each presentation before you use it. To see how to set up two presentations to run at the same time as pictured above, see my guide here .

Why bother changing the pointer color?

The most important reason to change the color of your pointer, is so that it stands out against your slide background.

Notice in the picture below, how much clearer the green laser pointer is against the red slide background, than the red one is. If your audience cannot see the color against your slide background, then using the laser pointer is meaningless.

The same would be true if you were using a blue or green presentation background.

In short, you want a high contrast between your pointer color and the PowerPoint background color you are using for your presentation. That way your audience can clearly see what you are trying show them.

So that’s how to use PowerPoint’s built-in laser pointer and change its color between red, green and blue to have high contrast against your presentation.

This is one of those cool PowerPoint features that few people know how to use. And now that you know how to use it, you can take advantage of it during your presentations.

Presentation Transcript

FreeElectron Laser

FEL • A free-electron laser, or FEL, is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses some very different operating principles to form the beam. Unlike gas, liquid, or solid-state lasers such as diode lasers, in which electrons are excited in bound atomic or molecular states, FELs use a relativistic electron beam as the lasing medium which moves freely through a magnetic structure, hence the term free electron.The free-electron laser has the widest frequency range of any laser type, and can be widely tunable, currently ranging in wavelength from microwaves, through terahertz radiation and infrared, to the visible spectrum, to ultraviolet, to X-rays.

Beamcreation

Beamcreation • To create an FEL, a beam of electrons is accelerated to almost light speed (technically known as relativistic speed). The beam passes through an FEL oscillator in the form of a periodic, transverse magnetic field, produced by arranging magnets with alternating poles within a laser cavity along the beam path. This array of magnets is sometimes called an undulator, or a "wiggler", because it forces the electrons in the beam to assume a sinusoidal path. The acceleration of the electrons along this path results in the release of a photon (synchrotron radiation). Since the electron motion is in phase with the field of the light already emitted, the fields add together coherently. Whereas conventional undulators would cause the electrons to radiate independently, instabilities in the electron beam resulting from the interactions of the oscillations of electrons in the undulators and the radiation they emit leads to a bunching of the electrons, which continue to radiate in phase with each other.[4] The wavelength of the light emitted can be readily tuned by adjusting the energy of the electron beam or the magnetic field strength of the undulators.

Holografija • Holography was discovered in 1947 by Hungarian physicist Dennis Gabor (Hungarian name: GáborDénes) (1900–1979),work for which he received the Nobel Prize in Physics in 1971. It was made possible by pioneering work in the field of physics by other scientists like MieczysławWolfkewho resolved technical issues that previously made advancements impossible. The discovery was an unexpected result of research into improving electron microscopes at the British Thomson-Houston Company in Rugby, England, and the company filed a patent in December 1947 (patent GB685286). The technique as originally invented is still used in electron microscopy, where it is known as electron holography, but holography as a light-optical technique did not really advance until the development of the laser in 1960.

Confocalmicroscopy • Confocalmicroscopy is an optical imaging technique used to increase micrograph contrast and/or to reconstruct three-dimensional images by using a spatial pinhole to eliminate out-of-focus light in specimens that are thicker than the focal plane. This technique has gained popularity in the scientific and industrial communities and typical applications are in life sciences and semiconductor inspection.

What is fluorescence If you shine light on some molecules, you may see light of a different color emitted from those molecules. This is known as fluorescence. The molecules absorb high-energy light (blue, for example). This increases the energy of the molecules, represented as the top black line in the diagram (an "excited" molecule). Some of the energy from the blue photon is lost internally (represented by the red squiggly arrow in the picture). The molecule then emits a photon with less energy, green in this example. Fluorescein is a common dye that acts in exactly this way, emitting green light when hit with blue excitation light. The color of light emitted is material dependent, and likewise the excitation light wavelength depends on the material. (There are other forms of inelastic scattering; fluorescence is particularly strong.)
