Abstract

PURPOSE:To lower the temperature of electrodes and reduce their wear by oxidation, by providing a by-pass between a laser medium gas path having a discharge gap and outside of this path and by gas-cooling a cathode projecting in the path by the pressure difference between inside and outside of the path. CONSTITUTION:A laser medium gas path is enclosed in container 1, in which laser medium gas containing carbon dioxide gas is filled. This path consists of suction duct 8, having filter 9, which rectifies gas, and exhaust duct 10, having heat exchanger 11 and axial-flow fan 12. Inside the path wall between these, anode 3 supported by insulator 4, and cathode 5 supported by insulator 7 are placed opposite to each other, and thereby a laser oscillator unit is formed. In this structure, insulator 7, which supports cathode 5, is provided with a cooling chamber which surrounds electrode 5. Here, No.1 ventilation port 17, which opens outside the path, and No.2 ventilation port 19, which opens inside discharge gap 6, are formed. In this way, gas is caused to flow by the pressure difference between inside and outside of the path, and thereby electrode 5 is cooled.
