技术参数
technical parameter
Select high purity and low absorption of fused silica glass (HERAEUS or CORNING) processing, with high density coating process requirements, to ensure that the damage threshold can reach 20 J/cm2 @1064nm 10ns, 20Hz, mainly used in high power fiber lasers and amplifiers of high power devices. Meet the requirements of mid-range fiber lasers.
CORNING、HERAEUS, Fused silica glass, high purity, low absorption.
 
Polished surface roughness up to 3Å.
High damage threshold can be reached, and can be used for 6KW high power laser.
