What is the point of a powerful laser?
The problem now is that semiconductors have made photons understand that from now on, they must fly around in the form of red photons. A. Buy a laser pointer. Blue is now complete. For blue, Photon still needs to do some work. The second semiconductor laser initially converts red light into infrared light that is invisible to humans. The high-power green laser pointer is becoming more and more popular. The green laser pointer is an astronomical observation assistant, pointing at stars and celestial bodies. Green lasers that emit in the green part of the spectrum are widely available to the public in a wide range of output power. Compared with other wavelengths of the same power, green lasers emitting at 532 nm (563.5 THz) are relatively inexpensive and are very popular due to their good beam quality and very high apparent brightness. Green lasers have a wide range of applications, including pointing, lighting, surgery, lasers, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons, and bird control.

Technically? It is possible to go to the end of the universe (there is such a thing). But in fact it depends on the laser pointer. Now, some foreign "laser pointers" are powerful, just like lightsabers, like you can see, dust particles scattered in the atmosphere. Most laser pointers produce milliwatts of power, which, if very collimated, is very useful for driving miles. The green high powered laser emitting at 532 nm (563.5 THz) is relatively cheap and very popular due to its good beam quality and very high apparent brightness. Green lasers have a wide range of applications, including pointing, lighting, surgery, lasers, spectroscopy, interferometry, fluorescence, holography, machine vision, non-lethal weapons, and bird control. But what is the point of such a powerful laser? “By shooting targets, we will create new and very valuable extreme pressure and temperature conditions for physicists,” explains Philip Martin, director of the Interaction, Dynamics and Laser Laboratory. We will explore the completely untouched field of light-matter interaction. "
