Abstract

The study describes a method that, with a series of experimental data obtained from a single sample, allows not only to estimate the threshold fluences but to take into account statistical nature of surface-damage. In a number of experimental situations this method makes it possible to estimate damaging fluences even from the result of a singular exposure of the studied surface. Estimated threshold. Fluences for various optical elements are presented: K8-glass, experimental phosphate laser glass KGSS-0180, high-reflecting and anti-reflecting thin-film coating of elements. Half-height duration of 1.06 micrometers - radiation pulse of 4 ns and irradiation spot of approximately 4 mm in diameter were used in the experiment.
