- Abstract
A laser correlation study of irradiation damage is carried out on the basis of anodized functional films with the aim of improving the stray light absorptivity in the framework of high-energy laser systems and reducing the contamination of the system after irradiation damage. An experimental study is performed to investigate the effect of different laser characteristics (wavelength, spot diameter, energy and incident angle) on the damage of functional films. On this basis, the damage evolution process was analyzed using ABAQUS secondary development and was in good agreement with the experimental results. In addition, the damage mechanism of the film system is discussed. This study can provide guidance for the optimization of the functional film system, as well as a reference for the design of the main optical path of the high-energy laser system.
