Paper Abstract

A comparative analysis of the efficiency of generation of the second harmonic of a TEA CO-2) laser in Te, ZnGeP2, GaSe, AgGaSe2, and Tl3AsSe3 single crystals as well as of the absorption properties of these crystals and the damage threshold of their surface has been performed on the basis of experimental data. High-optical-quality AgGaSe2 crystals holding much promise for the second harmonic generation have been grown. Phisico-chemical features of the process of growing and annealing of these crystals were investigated. It was revealed that the efficiency of the conversion of the CO2 laser radiation in ZnGeP2 and AgGaSe2 crystals can be significantly increased at the expense of shortening of laser pulses, which can be effected by a simple optical device -- a plasma gate.
