YAG is an earlier laser crystal. Because of its good basic properties, Nd: YAG is still widely used in near and far infrared solid-state laser and its frequency doubling and frequency tripling applications.
Main advantages:
· Low laser threshold
· High gain, high power
· Good optical properties
· The absorption of 1064nm light wave is less
· Good thermal conductivity and thermal shock characteristics
· Suitable for various working modes (continuous, pulse, Q-switch, mode locking)
