2022 Laser Pointer Opens Up New Frontiers
Laser pointers are affected by high temperature and air, and the laser beam tends to be 2-point or dim. As the temperature increases, the light from the laser pointer becomes better and clearer. Handheld laser pointers have attracted interest since their inception. When I saw an acquaintance's coach using a blue high-power green laser pointer, the visibility was very good, so I bought it immediately. Of course, I am satisfied with the excellent visibility of this laser pointer. Laser pointers are very convenient. The pointer of the 30000mw blue laser, the visibility of the light spot is good, but the price is more than 50,000 yen, which is quite a high image, but first and foremost is the clear application you need. Low power red, blue and green laser pointers are commonly used in classroom presentations, lectures, lectures, PowerPoints and business meetings where a laser pointer with a short visible laser beam is sufficient. Green laser pointers in the 50mW to 150mW range are always very popular in astronomy. Visible and bright laser beams ahead are useful for astronomy researchers, astronomy enthusiasts, sky and star demonstrations.

Distinguish various types of laser pointers from the function
Most laser pointers have the same functions, such as pointing, pointing from a distance, and teacher classroom use. There are toys, many people use it to entertain and play with their pets, you need to use other functions depending on the power. For example, crow laser pointers require specific powers and wavelengths to effectively fend off birds. The complexity of this process makes these laser pointers inherently unstable and inefficient, with outputs ranging from 1 mW to about 10 mW, It fluctuates widely with temperature, often with overheating or undercooling and mode jumps. That's because such a complex process can require temperature stabilizers and active cooling, which can't be installed on a small host. Handheld high power laser pointer have attracted interest since their inception. The red laser pointer is the first handheld laser pointer on the market, and with the development of new technologies, mass production of the handheld green laser pointer is possible. 2022 opens up a new millennium and a new frontier for amateur lasers. Today, the technology has advanced to the point where the U.S. military has a weapon sight that can blind a target at a distance of 2.5 miles, or 4 kilometers, using a 250-milliwatt green laser.
