GAS LASER

FIELD: quantum electronics, possible use for creating wave guiding two-channel gas lasers with collapsible U-shaped resonator with high power level of radiation. ^ SUBSTANCE: gas laser contains adjustment device. Adjustment device includes first and second bushings. Each bushing consists of serially positioned flanges with adjusting screws, portion with deformable neck, constituting upper portion of adjustment device, and clamping portion. In flanges of first and second bushings, respectively, hollow cylinder and cylinder-shaped rod with base are positioned, with internal portion of adjustment device positioned on each one of them and having a gap with portions of deformable neck and clamp. Internal portion of adjustment device for hollow cylinder is made in form of base with aperture and mirror with covering, non-transparent for laser radiation. For cylinder-shaped rod with base aforementioned internal portion is made in form of diffraction array or mirror with cover, highly reflective for laser radiation. Mirror is positioned on base in front of second discharge channel. Cylinder-shaped rod is made with hollow along axis, wherein an insert is positioned made of material with high thermal conductivity coefficient. ^ EFFECT: possible production of wave-guiding two-channel gas laser with U-shaped resonator, providing for high level of power of laser radiation. ^ 3 cl, 7 dwg
