Modeling of pulsed-laser cleaning of a gold mirror surface

摘要

A detailed model is presented for the pulsed-laser cleaning of a gold mirror surface. Temperature dependencies of the substrate thermal and optical constants were considered since these constants are sensitive to thermal variations, particularly at cryogenic temperatures. Computations of the heating of the substrate were done in order to ascertain damage thresholds. Calculations were also done for the heating of films on the metallic substrate that were either totally absorbing or totally transparent to the laser radiation. Comparisons of theory with experiments are made.
