| Реферат: | eng: We report results on comparative study of SHG in powder of promising nonlinear gamma-Ga2S3 crystal. Digallium trisulfide powders with particle size from 20 mu m to 500 mu m were tested in comparison with powders of well-known LBO, BBO, KABO, KDP, and LN nonlinear optical crystals under the pumping by a 7 ns 1064 Nd: YAG laser. Laser-induced damage threshold of different powder fractions were determined. Powder of gamma-Ga2S3 shown high damage threshold and large SHG intensity: 56 times to that in LBO powder, 15 in BBO, 50 in KABO, 67 in KDP, and 3 in LN (for particle size: 20-50 mu m), that renders it amongst the most promising crystal for frequency conversion of high-intense nanosecond radiation of near-IR lasers by optical rectification technique.
