[0002] Laser, full name "through the light amplification by stimulated emission" is a special light. Its main difference from traditional light is that laser beam has monochromaticity, unidirectionality and coherence characteristics. These characteristics make the light with extremely high focusing performance invisible to the naked eye, and the brightness is 100 times that of ordinary light source.
