GASEOUS-DISCHARGE CO LASER Russian patent published in 2000 - IPC

FIELD: laser equipment. SUBSTANCE: invention is related to devices with stimulated emission. Gaseous-discharge CO laser of high pressure with subsonic flow of working gas includes heat exchanger, discharge chamber with heteropolar electrodes connected to high-voltage generator and resonator placed across output of discharge chamber. System of conductors each being located inside capillary dielectric tube is used in the capacity of electrodes. Gap between capillary tubes is less that their diameter. Axes of tubes are perpendicular to vector of flow of working gas. Heat exchanger is aligned with capillary tubes by communication of their space to source of cooling agent. Conducting coat on internal surface of tubes can be used as conductor. EFFECT: enhanced efficiency of laser, energy displacement towards short waves in emission spectrum is achieved. 1 cl, 4 dwg
