I am looking at how to use the thin laser pointer beam

I’m not entirely sure what you mean is that thick and wide are two different things. My view on the product described in her link is a device that uses an IR green laser pointer diode as an illumination source, and uses an adjustable zoom lens type device to spread the light from the laser source to…

A more powerful laser will produce a brighter scattered beam

If you see a point or a beam, you have a visible laser. Whether you see a light beam in the air depends on several factors: In clear air, the light beam will be scattered by air molecules in a process called Rayleigh scattering. The process is fairly weak and depends on atmospheric pressure, green laser…

The green laser pointer still has a relatively safe power level

If you mean under “normal” conditions, that is, there is not much dust in the air, and the humidity is within the normal range, then it largely depends on the wavelength. The shorter wavelengths are more dispersed in the air molecules (the presence of gas) than the longer wavelengths. Dispersion is the cause of the…

You need to know that a laser pointer is a focused light

It may end with a star, as if it is widely exaggerated to think that space spans infinity, which may be true, but in our case, think of space as a collection of celestial bodies and gaps in between. So at some point, there must be a star in the green laser pointer path. If the star…

There is currently no treatment that can repair pen damage

I accidentally looked at a green laser pointer spot for about a second, and now there is a blind spot in the middle of my field of vision. Is this permanent? If you look at the light spot reflected/scattered from the wall or paper, and the distance is more than 5 feet, and it is not a…

This is a real modern laser pointer weapon

I am tired of lasers. Can you think of an original sci-fi weapon with physically possible effects? There are many good answers here, but I will add: What about the green laser pointer that really work? If no medium can pass through, they are invisible, and they actually travel at the speed of light. You just stand…

The airborne laser is the most ambitious laser pointer

What is the best laser? Well, usually putting a laser pointer on a rifle is a bit unnecessary. However, if you really want one, I suggest you use PEQ. These are a little heavier than a single laser, but it is one piece. It is a flashlight, a red laser, and most importantly an infrared laser. There…
