激光预处理对BaF2薄膜损伤性能的影响
Influence of Laser-conditioning on Laser Induced Damage Capability of BaF2 Thin Films
摘要
Abstract
In order to enhance the laser induced damage capability of optical films components, besides advanced methods and processes, post-treatment has significant influence on the laser induced damage threshold (LIDT) of thin films. Q switch Nd:YAG laser of the working wave length at 1064 nm,was used to post process on BaF2 single layers with thickness of λ/2 (λ = 1064 nm) deposited by electron beam evaporation, and the laser induced damage properties were investigated. By changing the energy density and pulse number under the spot size remained a fixed value, their effects on thin films damage threshold were studied respectively, the optimal processing parameters were obtained: energy density is 9. 9 J/cm2 and pulse number is 3 times. The LIDT of post processed BaF2 films was improved from 16. 5 J/ cm2 to 29. 9 J/cm2.关键词
