PURPOSE:To control temperature increase to obtain high efficiency and high characteristic output, by rectangularly crossing discharge current and gas flow with laser optical axis with the density of N2 six times or more of CO gas to increase gas pressure to 20Torrs or more. CONSTITUTION:A rectangular laser tube 1 consists of the upper tube wall 2 and lower tube wall 3 and the rectangular hollow duct part 4 formed therebetween. A planar anode electrode 6 is buried in the lower tube wall 3. Besides, an insulating material 7 is buried in the upper tube wall 2, and a plurality of hollow holes 8 adhered with a cylindrical cathode electrode 9 to the inner boundary thereof are linearly separated with each other. When the gas flow 5 is introduced into the inside of the duct 4 after the evacuation of the inside of the laser tube 1 to impress the voltage of 400-1kV between the electrodes, laser light is generated in the direction orthogonal 16 to that of gas flow and discharge current. Said CO mixed gas should be six times or more in the density of N2 with the whole pressure of 20Torrs or more.
