Nd:YAG

Nd: YAG single crystal is the most important laser crystal, which is widely used in industrial, medical and scientific fields. The main advantages are: low output threshold, high gain, high efficiency and low 1064 nm loss; At the same time, it also has the characteristics of high optical quality, good thermal conductivity, thermal shock resistance and high mechanical strength, which makes Nd: YAG the most suitable and commercial laser crystal for continuous, pulse and mode-locked laser. Nd: YAG crystal is also widely used in various solid-state laser systems: frequency doubling continuous wave, high-energy Q-switch, inverted cavity and so on.
