Paper Abstract

Single shot LIDT of single layer coatings of different deposited materials (SiO2, HfO2, Ta2O5 and Nb2O5) have been studied. We report dependence of the damage threshold with different operational and material parameters (pulse duration, nature of the deposited material, deposition process or thickness of the layer). For interpretation a model dedicated to optical coatings and based on the conduction band electron rate equation is used. The simulations are compared to experiments. The theoretical approach is in good accordance to the experimental data.
