ELECTROOPTIC LASER UNIT WITH GAS CROSS FEED Russian patent published in 1998 - IPC

FIELD: laser equipment. SUBSTANCE: device has gas-discharge chamber which has at least one discharge gap and reversed or non- reversed electrode systems as well as multiple-pass optical resonator with back blind mirror, front output system and reversed or non- reversed rotation units. power of adjacent rotation units and direction of transmission of laser beam through them may be perpendicular. In addition one rotation unit may be perpendicular to gas flow for specific combination of rotation unit type and type of electrode systems. Number of laser beam passes is factor of four. EFFECT: increased uniformity of temperature and intensity across laser beam section. 12 dwg
