Laser Induced Damage

With the development of high power laser systems, laser protection of optical components becomes more and more important. 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 1064nm, was used to post process on ZnSe single layer films with thickness of /2 (=1064nm) deposited by thermal evaporation, and the laser-induced damage and optical 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 3.0 J/cm2 and pulse number is 1.The LIDT of post processed ZnSe films was improved from 5.0J/cm2 to 8.2J/cm2.
