Paper Abstract

Laser-induced damages on optical components will cause wavefront modulation effect and further influence the downstream propagation of transmitted beam. In this paper, a method named polygon-binaryzation modeling (PBM) is applied to describe this effect taking place on dielectric coating. Both theoretical and experimental studies are carried out. In theory, the principle of PBM is introduced. Downstream beam propagation behind damage site could be simulated based on the wavefront model. In experiment, a pump-and-probe testing bench is designed. Wavefront properties of coating damages with opaque and transparent morphologies are detected. Furthermore, based on the experimental parameters, PBM is simulated. The good match between simulation and experiment demonstrates the validity of our method.
