What fun will happen to the restar laser pointer?
Lasers from a laser pointer can burn the retina of the human eye. The danger is obviously greatest if the beam is aimed directly at the eye, rather than simply scattering from the beam and looking at it from the side. The danger depends on the wavelength of the laser beam, the output of the laser designator, the divergence of the laser beam, the distance between the person and the indicator, whether the beam is seen directly or through reflection, and the length of the beam. Whether it shows the human eye's natural "blinking response" to bright light. The green light is scattered from the direction of the beam by air molecules and dust particles (thus allowing the beam to be seen from the side). Eyes are particularly sensitive to the green laser pointer. This makes the green laser pointer the most popular portable laser technology in the world. Green laser Pointers are known for producing the strongest and brightest laser beams everywhere.

Need a high-powered green laser pointer? Do you only use green high powered laser Pointers in demonstrations? How far do you want the laser pointer beam to be visible? All of these issues need to be considered before deciding when to obtain a laser designator. Laser pulses cannot generate ultra-short, high-power laser pulses in one step. Therefore, short pulses must first be generated and then amplified to the desired power level. However, you need to generate pulses of less than 100 FS, or a millionth of a second. Therefore, laser designator crow materials that can emit light in a very wide band (spectral width of tens of nanometers) are selected and the cavity is constructed so that the laser effect can be achieved in the whole wavelength range, i.e., multi-mode. All of these patterns need to be synchronized. Only when they are all fired at the same time is the transmitted pulse shortened. However, each of them is randomly synchronized according to the spontaneous radiation that produced it.
