Abstract

The inclusion model of laser initiated damage is extended to include an arbitrary but repetitive and reproducible variation of the laser irradiation in time. The controlling influence of the thermal properties of the film/substrate system and inclusion, together with the duty cycle of the laser, i.e., the duration and energy of a single pulse and of the repetition rate, on the damage threshold is discussed. The predictions of this model are then compared to the results of the single-shot model of inclusion dominated damage. Suggestions for experimental tests of this model are given.
