Nd Yag Laser Rod 1064nm Laser Rod
Nd Yag Laser Rod 1064nm Laser Rod
Nd: YAG crystal is currently the best solid
state laser material with high gain, low threshold, high efficiency, low loss, good thermal conductivity and thermal shock resistance. It is suitable for a variety of laser operation modes (continuous, pulse, Q-switch, mode locking, frequency doubling, etc.), and is widely used in industry, medical and scientific research fields
