PREDICTION OF RADIATION RESISTANCE OF NANOSIZED COATINGS

In the course of studying laser ablation destruction of various materials, one of the challenges for researchers is the prediction of the radiation strength of such materials. A great interest in laser ablation of thin-film coatings and optical materials (glasses, crystals, optical fiber and other optical elements) is due to their wide application in nanophotonics and optoelectronics for various purposes when they are subjected to high-power laser radiation. The problems of predicting the dynamics of the optical strength of such samples are considered in this paper using Weibull statistical distribution. In this paper, we investigate a method of determining the radiation strength of transparent materials from the results of their laser ablation destruction based on Weibull statistical distribution for predicting the time of their failure-free operation.

Keywords: radiation resistance, radiation strength, laser ablation, Weibull distribution
