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…

Never point the laser pointer can be in the eyes

How much power does the laser pointer need to emit a visible beam? This is not a question of power, which is equal to the intensity of the laser. A more powerful green laser pointer will make the spot farther and brighter. The laser line used in the building is a spot of light “diffused” through a…

Your laser pointer beam can go into space

Laser is a high-energy coherent and extremely concentrated focused electromagnetic wave. But it will eventually pay remotely. I am not a green laser pointer expert by any means, but I think one of the reasons is that the beam itself consists of multiple wavelengths. There are countless wavelength starting points between any two consecutive peaks in the…

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…

The laser pointer beam behaves differently from other light sources

How accurate is the laser tape measure? More accurate than steel belt. When you measure a distance greater than about 3 meters, the tape will inevitably sag, so the measurement is not very accurate. green laser pointer measurement working at the speed of light does not have any sagging. Obviously the cheaper model is not accurate, but…

Is it possible to destroy the earth with a laser beam powerful enough?

Can laser treatment really reverse scalp hair loss? green laser pointer treatment may thicken existing hair, thereby inhibiting the temporary growth and density of hair. The only three ways to increase hair density are hair transplantation, hair micro-pigmentation (creating the illusion of shaved head/creating dark shadows between existing hair) or wigs. Is it possible to destroy the…

Can a laser pointer shoot down a drone?

If you really use a powerful laser, you have an aid to aim directly at the camera, if the remote pilot uses trans-horizon/first-person vision, then he will be forced to use the map to navigate and eventually go home. It will be very difficult. Compared with manned aircraft, green laser pointer are much more harmful to drones….

The laser pointer beam is located inside the fiber

Can you pass a safety laser with a mirror? You mean like in the movie? Who designed such security? That is a defeated system. Let me give an example of a safety laser. The optical fiber is buried in the gravel “moat” surrounding the facility. Fences are usually used with optical fibers. The laser pointer beam is…
