Paper Abstract

The present report gives an account of experimental investigations of coatings damage under laser radiation (LR) action. Q-switch modulation ((tau) i0,5 equals 30 ns) and free generation (total impulse duration (tau) i equals 170 microseconds) regimes of Nd-laser working were used in the experiment. The energy thresholds are determined for seven samples with different coatings. Some notes to research test scheme, principles of results processing, physical description and discussion of research results are contained in this paper.
