建立了用于光学元件和材料的激光(1064 m与355 nm)损伤阈值测试平台.按照IsO-DIS 11254-1.2的测试规范,采用l-on-1打点与激光损伤几率的方法给出被测样品的激光损伤阈值.研制了激光光斑有效面积测试装置,提高了光学元件激光损伤阈值的测试精度.

A platform for laser (1064 nm and 355 nm) induced damage threshold test of optical elements have been established. According to the international standard "ISO/DIS 11254-1.2” adopted, one shot on each unexposed site on the sample surface (1-on-l) and a new method of laser induced damage probability have been adopted. The laser induced damage threshold test accuracy has been increased by using a effective area test system in platform.
