YAG lamp-pumped laser marking machine uses krypton lamp as energy excitation, ND: YAG as working medium to generate laser. The light of certain wavelength generated from excitation can make the working materials occur energy level transitions, and then releasing the laser, as a result, it will release laser beam to process the target material. YAG laser is a kind of solid-state laser, which produces laser of 1064nm wavelength. It belongs to infrared light spectrum, which is characterized by high vibration efficiency, large output power, and good stability; these characters make it a solid-state laser of the most technologically sophistication and the widest range of applications.
