Common industrial laser types include solid-state lasers, CO2 lasers, and fiber lasers. With the continuous breakthrough of laser technology, the power has been continuously improved, the application fields of lasers have become wider, and the division of labor of lasers has become clear. However, t
The damage caused by light is mainly due to the temperature effect and photochemical reaction caused by its absorption of energy, which causes biological damage. The primary mode of damage depends on the wavelength of light and the tissue exposed. For the hazards of lasers, the main cause of damage
