GAS LASER Russian patent published in 2009 - IPC H01S3/00 

FIELD: electronics.

SUBSTANCE: invention is attributed to quantum electronics specifically to gas lasers. Gas laser comprises microwave oscillator, waveguide line for microwave oscillations transmission, electrodischarge section, optical resonator. The laser is provided with discharge channel with combustion chamber at its inlet, unit for mixing working gas with ballast gas and nozzle unit. At the outlet of discharge channel there is system for gas exhaust and its utilisation. Electrodischarge section is comprised by two lengths of trough waveguide the longitudinal axes of which lay in one plane with longitudinal axis of discharge channel. Slits of trough waveguides are interconnected; there are coupling holes in the area of trough bottom of each trough waveguide to power discharge section from microwave radiation energy. Trough waveguide lengths are limited in longitudinal direction by short-circuiters with beyond-cutoff holes coaxial to mirrors of laser optical resonators.

EFFECT: lowering of active media pumping power threshold, increase in output power of optical radiation, lowering of mass-dimensions characteristics, increase in continuous work time of laser.
