Is handgun with laser pointer safe?
The biggest difference is that lasers emit coherent light, while leds emit only colored light. So the LED lights up like a candle, while the laser emits a beam of light. A semiconductor laser is a laser similar to an LED. Some lasers emit specific wavelengths. And there are many lasers that emit visible and invisible spectra. Compared to leds, the emission spectrum is very narrow. You can find the answer in any book on laser physics. Laser is a device that emits light by stimulated emission of electromagnetic radiation through a process of light amplification. The term "laser" comes from the acronym "radioactive light amplification". High pressure allows independent and reactive gases to be produced at the right temperature and coherent light for optical focusing and orientation. If very low power is selected, the laser beam will not be visible at night or during the day. The 532nm green laser designator beam of up to 30mW is clearly visible. You can also see green laser beams indoors during the day. Laser designators with higher output power produce increasingly powerful green laser designator beams.

The highest power laser Pointers always have higher burning power. The green laser pointer rises by 100MW, which is conducive to combustion matching. The 200MW laser pointer can burn cigars, cut tape and pop balloons. There are a variety of color laser Pointers on the market, such as red laser Pointers, green laser Pointers, blue laser Pointers, blue and purple laser Pointers. So today I want to talk about some different colors of lasers that have different uses. More people also know about red laser Pointers. Red lasers are mainly low-power and are commonly used for education, such as projection and business meetings. Red dots are warm colors, not very bright.
