Green laser marking machine is one kind of the laser marking machines which is widely used to mark on the surface of glass and crystal.
Different from the semiconductor end pump laser marking machine, the green laser marking machine is side-pumping. Sine the green laser machine has a wavelength of 532nm green laser output, the diameter of focusing spot is smaller with more energy. Thus, the photoelectric rate is higher. Green laser marking machine is suitable for marking on the surface of glass products, such as cellphone screen, LCD screen, optical devices, automotive glass, etc. It can also be applied to a majority of metal and non-metallic materials such as hardware, ceramics, glasses watches, PC, electronic devices, PCB boards and control panels, nameplate panels, plastics, etc.
