The proposed gas laser has the following construction: the resonator mirrors (1, 2) are supported by an elongated hollow body (3) which consists of a material having a thermal coefficient of expansion alpha 1 < 5 x 10<-7 DEG >K<-1>. The complete resonator unit is supported in a sprung manner in a vacuum sleeve having an alpha 2 > 30 x 10<-7 DEG >K<-1>. Electrodes (5, 6) are passed through the sleeve, which electrodes approach one another in the gas space outside the resonator in such a manner that - in accordance with Paschen's Law - the gas discharge always takes the detour through the mirror body. In a preferred exemplary embodiment, the electrodes (5, 6) contain pins (17, 18) which in each case project into a side opening (10, 11) of the hollow body (3) and are connected to a metal strip (19, 20), which points toward the opposing electrode, on the inner wall of the sleeve. <IMAGE>
