Laser-Induced Damage Threshold of Barium Chalcogenides Crystals at 2091 nm

This paper is devoted to a determination of the 0% probability laser-induced damage threshold of the BaGa4Se7 and BaGa2GeSe6 nonlinear elements by the R-on-1 procedure. A Ho:YAG laser radiation at 2091 nm with pulse duration 13-17 ns and varied pulse repetition rate, 2 kHz, 5 kHz and 10 kHz, was used for testing.
