Laser induced damage characteristics in fused silica surface irradiated by 1064 nm and 532 nm ns laser simultaneously

  • 摘要: 利用Nd: YAG激光器研究基频(1064 nm)与倍频(532 nm)单独辐照和同时辐照下熔石英的损伤规律,对损伤几率进行了测试,获得损伤几率曲线与典型损伤形貌。研究结果表明:双波长同时辐照下的初始损伤阈值总是小于单波长辐照下的初始损伤阈值;基频光中加入定量倍频光后,熔石英对基频光的吸收效率提高;并且双波长同时辐照下,熔石英损伤密度增大;原因主要是熔石英表面缺陷对不同波长吸收机制的差异。
