TWO-BEAM GAS LASER Russian patent published in 1994 - IPC

FIELD: quantum electronics. SUBSTANCE: two-beam has laser has discharge tube with active medium and optical resonator with two crossing arms. Rotary mirror manufactured in the form of phase-anisotropic unidimensional wire grid is installed at point of crossing of their axes. Butt half-wave phase elements manufactured in the form of dihedral mirrors with 90 degrees angle between edges are mounted in butt of each arm. Half-wave phase elements are provided with means of turning about axes of arms of resonator. EFFECT: enhanced operational efficiency. 1 dwg
