ELECTROOPTIC LASER UNIT WITH TRANSVERSE PUMPING OF GASEOUS WORKING MIXTURE Russian patent published in 1997 - IPC

FIELD: laser equipment. SUBSTANCE: proposed electrooptic CO₂-laser unit has rear blind mirror, turning assemblies, and front reflecting output mirror system of cavity secured in tandem in first air gap on cavity plates along laser beam which ensure at least two generator passages of laser beam and one amplifier passage up to angle mirror reflector; installed in second air gap on cavity plates are turning assemblies affording at least three amplifier passages of beam from angle mirror reflector to beam output assembly; at least one turning assembly in each air gap is made in the form of mirror prisms turning laser beam through 180 deg. EFFECT: improved efficiency of laser unit and characteristics of laser beam. 3 cl, 7 dwg
