The influence of several lasers on the organs

??????The most widely used lasers currently include: carbon dioxide laser (CO2Laser) and fiber laser (FiberLaser), with wavelengths of 10.6um and 1.07um, respectively, which belong to the far infrared and near infrared range. Most of the laser application system power is 10W-4KW, there are higher or lower power used in civilian and military or medical. In the general laser safety standards, the application system of lasers greater than 0.5W has to implement four types of laser safety standards. There are strict requirements in the safety management and operation specifications of equipment management. The principle of laser damage to human skin pigments. Lasers with different spectrums have different effects on body organs. Near-infrared and visible light can reach the retina directly, and directly to the retina, causing irreversible damage to the optic nerve. Synchrotron radiation and laser combination: Electromagnetic spectrum area Wavelength range Organs affected UV radiation 200-400nm cornea, lens, skin UV-C 200-280nm cornea and conjunctiva total absorption Ultraviolet-B 280-315nm basic full-absorption cornea-conjunctival cataract Ultraviolet-A 315-400nm crystals are fully absorbed to form cataracts Visible light 400-780nm retina Near infrared 780nm-1.4um retina, crystal, skin Infrared-B 1.4-3.0um cornea and skin Infrared-C 3.0um-1m cornea and skin
