Abstract

The sensitivity of the pulsed laser induced damage threshold of optical thin films to the thermal and optical properties of the film, substrate and included materials are studied within the context of inclusion-dominated damage models. Two models are considered. In one, a spherical inclusion is embedded in an infinite host. The absorption cross-section for the incident laser radiation is calculated using Mie scattering theory. A diagram of the model including all of the relevant paramters is shown in Fig. 1.
