Paper Abstract

The mechanisms which cause a damaging interaction between laser light and optical materials are reviewed. Their dependence on laser pulse duration and wavelength is discussed and available experimental results for short pulse damage thresholds are presented. It is shown that localized absorption in coatings, surface defects, or impurity inclusions generally determines the practical irradiance limit. Intrinsic non-linear processes such as avalanche breakdown or two photon absorption set the upper limit to the safe irradiance level.
