SINGLE-CRYSTAL MATERIAL FOR LASERS OF INFRARED BAND

摘要

FIELD: materials for laser equipment, in particular, single-crystal materials designed for production of active components of solid-state lasers. SUBSTANCE: erbium with chemical formula Ca_aY_1-x-yYb_xEr_y(BO₃)₃O, where x0,001, y0,001, x+y≤0,57, is additionally introduced as an activator in the single-crystal laser material based on oxyorthoborate of calcium-yttrium with ytterbium. EFFECT: produced active components of the 1.5- micron radiation band. 4 dwg, 1 tbl
