What can lasers bring to you?

The characteristics of blue, green and purple laser pointers: the irradiation point of the Laser pointerLaser pointer not only depends on the output power and apparent brightness of the laser reflected from the surface, but also depends on the color version of the human eye. For example, the human eye is most sensitive to wavelengths in the visible spectrum from 520 nm to 570 nm, but less sensitive to red and blue laser wavelengths. Therefore, the 532 nm green laser is brighter than other color lasers with the same output power. Laser welding: Sealed devices such as automobile body thick and thin plates, automobile parts, lithium batteries, cardiac pacemakers, sealed relays, and various devices that do not allow welding pollution and deformation. The lasers currently in use include YAG lasers, CO2 lasers and semiconductor pump lasers.
