Strong laser pointer market
About five years ago, very powerful green laser pointer came onto the market. New technologies and innovations have enabled yellow Laser technology to be manufactured into portable laser devices, a precursor to the Yellow laser pointer. Gadget lovers and laser enthusiasts can now buy yellow light and yellow light lasers at a lower price than before comparison. The DPSS laser and laser pointer technology turn the laser flashlight green so to speak to provide a piece of sunlight. The 593nm wavelength has turned yellow and is hard to manufacture, let alone trees, now enjoying the effect it's coming out of. Yellow laser Pointers are popular with hobbyists and manufacturers who want to develop their laser lines by adding more spectra. The wavelength at which lasers operate gives them their distinctive color. Laser safety glasses and goggles correspond to these wavelengths and are designed to filter out certain wavelengths. That's why laser safety glasses have so many different lenses; The correct lenses for specific lasers will filter harmful rays from these lasers, and it is important to customize laser glasses according to the type of laser used.

Using powerful laser parties on the star stage is usually a big problem, and when you get a star at any point in time, you suddenly get very excited. Astronomers must continue to control all airborne oxygen-carrying aircraft and take appropriate safety measures to protect eyes from radiation. Now the biggest problem that restricts laser projector, it is safety hidden danger, especially in open space, this one problem is more serious. Take the simplest laser pointer, which is a semiconductor laser with an optical lens in front for focusing. Everyone knows that you can't shine laser light directly into your eyes because the laser energy is so concentrated that it is very harmful to your body. For example, the Vanadate laser used in the theater has a maximum power of 20W and a luminous flux of 5000lum, which belongs to the fourth category of laser. If a trouper takes a lens, it is possible to burn things at a certain distance. A 150MW laser at a distance of 1 meter can easily burn our usual plastic film bag, some industrial cutting machine high powered laser power is only that much.
