Paper Abstract

In high-power laser systems, the optics suffers from different degrees of damage due to high-power laser irradiation. Studying the laser-induced damage generation and growth law of the optics is greatly benefited by the ability to accurately predict how damage sites evolve with laser exposure. In this work, the laser-induced damage growth model in optics under high-power laser irradiation is described based on the Weibull distribution model. A parameter method for solving Weibull distribution model by using the least-square method is proposed. In addition, a Monte-Carlo analysis method is used to numerically simulate the growth law of laser-induced damage in optics based on the statistical theory. Furthermore, we have also predict the laser-induced damage growth trend for 20 shots in high-power laser systems.
