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

FIELD: quantum electronics. SUBSTANCE: laser is made in the form of two parallel arms in which one or two discharge tubes and rotary mirror fabricated in the form of dihedral mirror with 45 degrees angle between edges and second rotary mirror are positioned. Second rotary mirror is made in the form of half-wave phase section composed of flat and unidimensional wire grid placed at distance d=, where l is wave length; n=0, 1, 2 . . . . Half-wave phase section is provided with mechanism of turning about axis perpendicular to its plane. Butt mirrors are produced in the form of unidimensional wire grids. EFFECT: expanded application field. 1 dwg
