PURPOSE:To contrive the improvement of the oscillation efficiency of a gas laser. CONSTITUTION:A gas laser is provided with a double tube 16 made of a dielectric, a gas circulator 5 which is connected to an inner tube of the double tube and supplies later medium gas, a cooling medium circulator 17 which is connected to an outer tube of the tube 16 and supplies a cooling medium having an insulator property, a microwave cavity resonator 1 encircling at least one part of the tube 16, a microwave generator 8, which is connected to the resonator, and a totally reflecting mirror 11 and a partial reflecting mirror 12, which are arranged in opposition to each other at both end parts of the tube 16. A discharge tube 2 is cooled in such a way, whereby the oscillation efficiency of the gas laser is improved. |
