GAS LASER Russian patent published in 1994 - IPC

FIELD: quantum electronics. SUBSTANCE: gas laser has active medium located in optical, resonator formed by half-wave phase element made in the form of 90 degrees dihedral reflector and two semitransparent anisotropic coupling reflectors manufactured in the form of unidimensional wire grids with equal transmission coefficients. Coupling reflectors are installed with mutual 90 degrees azimuth and are provided with mechanism of reverse movement along axis of laser. Azimuth of half-wave phase element amounts to 45 degrees with reference to each coupling reflector. EFFECT: improved efficiency of control over radiation polarization. 1 dwg
