Abstract

The coupling model of defect and organic contamination was presented to analyze the coupling effects on laser-induced damage and understand the damage degradation mechanism of optical films in a closed vacuum environment. The distributions of temperature rise around an absorbing defect in multilayer ZrO2/SiO2 films were computed based on the finite-element simulation. Laser induced damage tests were made to compare with the theoretical model. Test results were in an agreement with the presented model and calculated results of a temperature rise.
