A gas discharge laser including at least one electrode consisting of a rolled metal foil which is clamped in the tubular envelope of the laser. Spacers are provided between the foil and the inner wall of the envelope at regular distances from each other and may consist, inter alia, of pits depressed in the metal foil so that a rotationally symmetrical heat transfer from the electrode to the envelope is obtained. A thermally stable laser thus is obtained in which the generated laser beam has a substantially constant direction. |
