FIELD: laser engineering. SUBSTANCE: active elements of laser quantron are isolated from light pump source by coating filtering off ultraviolet radiation. This double-layer coating has first layer of cerium dioxide, 0.25-1.5 mcm thick, deposited on transparent parts of light pump source and/or optical parts incorporated in quantron reflector and separating light pump source from active medium. Second layer is made of silicon dioxide, 0.5-1.0 mcm thick, deposited on cerium dioxide layer. EFFECT: improved design. 1 dwg
