YAG+Er:YAG+YAG
YAG+Er: YAG+YAG bonding crystal is a bonding crystal formed by bonding pure YAG at both ends of Er: YAG, which can effectively improve the comprehensive performance of Er: YAG laser. Er: YAG thermal conductivity is 14w/m/ K@20 ℃. 10.5W/m/ K@100 ℃, the thermal conductivity of pure YAG crystal is 14w/m/ K@20 ℃ 10.5W/m/ K@100 ℃, both ends are bonded to form YAG+Er: YAG+YAG bonded crystal, which can effectively improve the thermal effect of Er: YAG crystal, reduce the thermal lens effect formed during laser pumping, improve the beam quality of laser, improve the output efficiency of 1600nm and 2940nm laser, …
