Paper Abstract

We describe in this paper a model to link laser damage initiators properties (nature, size distribution, density) to measured Laser Induced Damage Threshold (LIDT). It is based on calculation of light absorption in nanoabsorbers and subsequent heating, coupled to laser damage statistics in order to obtain the laser damage probability as a function of laser fluence. Applications to the case of optical coatings are then presented. We study the influence of laser irradiation parameters and coatings properties on LIDT measurements. By coupling this multiscale study to our model, we show that information on the initiating defects properties and the physical damage mechanisms involved can be obtained: discrimination between different defects, estimation of densities, size and nature of defects, evolution of the defects under multiple irradiation. Implication of this approach for physical understanding and metrology applications are discussed.
