摘要

We show that, in a vast class of multiple-pulse laser–matter interaction settings, the S-pulse laser damage probability and the expected number of pulses before the damage can be expressed in the S >  > 1 limit as closed-form functions of the laser fluence and the variation coefficient of laser-driver statistics. The statistics of such rare laser-damage events is found in the class of generalized extreme-event distributions, allowing multiple-pulse laser damage to be understood in terms of universal properties of extreme-event statistics. As a demonstration of its descriptive power, this approach is shown to provide an accurate, physically insightful fit for the reference experimental data for multipulse laser damage in optical-grade glasses and nonlinear crystals.
