Laser point power meter technology is getting better and better
A blue laser pointer of a specific wavelength, such as 473 nm, usually has the same basic structure as a DPSS green laser. In 2006, many factories began to manufacture high powered laser pointer modules for mass storage devices, and these modules were also used for laser pointers. These are DPSS type frequency multiplier devices. On the other hand, the laser beam hardly diffuses and maintains long-distance intensity. But with such a tight light, finding your way in the dark is not very helpful. Entertainment is one of the other applications of lasers. The most common use of lasers in entertainment is special effects used in laser shows. Clubs, parties and outdoor concerts all use high-power lasers for safety. Laser shows usually have lenses, mirrors and smoke.

I want to discuss the safety level of the laser. Responsible laser owners should take some time to fully understand the FAA regulations regarding the use of laser pointers. There are 5 levels of laser, the higher the level, the higher the laser power. The use of laser pointers is very common. The laser pointer is a useful tool for educators in classrooms and meetings. However, due to low cost and ubiquitous supply, these laser pointers are currently purchased and used by the general public, including children, and used in ways that manufacturers do not want. Therefore, there are serious concerns about the danger of laser pointers. However, laser pointers are of little use in the wider entertainment industry except for actual pointing, and there are many places where people with pointers are prohibited from entering as a potential hazard. It is rare to see professional dancers wearing laser gloves on the performance stage, which may be mistaken for pointers. Unlike pointers, they usually produce low-power, high-divergence beams to ensure eye safety. In magic performances, magicians use laser pointers as props.
