HIGH-POWER LASER WITH STABLE-UNSTABLE RESONATOR

摘要

FIELD: laser engineering. SUBSTANCE: laser has expanding active medium and stable-unstable resonator incorporating stability plane and instability plane perpendicular to the former. Laser beam output is effected by means of output mirror arranged for converging output beams while maintaining their parallelism. Resonator has low coefficient of magnification M (1 M,2) in instability plane. EFFECT: improved efficiency and output power; improved radiation characteristics. 6 cl, 3 dwg
