FIELD: quantum electronics, in particular, electric-discharge CO2 lasers. SUBSTANCE: device has discharge tube, which is mounted inside holding jacket, is made from beryllium oxide, and carries electrodes and mirrors of resonator, cooler, which is mounted on jacket, and air pumping system. In addition device has insulator, which is mounted on side on high-voltage electrode and is connected to jacket. Discharge tube is connected to insulator and to tank with additional working gas. Tank with additional working gas and pumping system are mounted on side of low-voltage electrode. Holes for passing air are provided on jacket member which is adjacent to insulator. Tank with additional working gas is designed as coaxial cylinder, which inner surface is designed as part of holding jacket. Jacket and tank with additional working gas are made from Kovar. Air pumping system has axial-flow fan. Outer surface of insulator is designed as cone frustum, which lower base is directed towards pumping system. Insulator is made from beryllium oxide. Outer surface of discharge tube is designed as regular polyhedron. Cooler is made from members, which length along discharge tube conforms to condition A ≤ L*h/H,, where L is length, and h and H are respectively tolerable and real curvatures of discharge tube for L. Cooler uses needles, which are uniformly arranged about cross section of air flow. EFFECT: decreased weight and size, increased functional capabilities, longer service life, simplified design. 9 cl, 3 dwg
