GAS LASER Russian patent published in 1994 - IPC

FIELD: quantum electronics. SUBSTANCE: gas laser has active medium placed in optical resonator formed by main anisotropic reflector and half-wave phase element manufactured in the form of 90 degree dihedral reflector. Additional anisotropic reflector is positioned between main anisotropic reflector and active medium. Anisotropic reflectors are placed at distance n(λ/2) from each other, where n=1, 2, 3...; λ is length of radiation wave. Azimuth between them is determined by relation given in description of invention. Azimuth between additional anisotropic reflector and half-wave phase element is equal to 45 deg. EFFECT: enhanced operational reliability and stability. 1 dwg
