ABSTRACT:
In a gas laser composed of a capillary tube made of electrically nonconductive material and presenting a capillary passage, a reservoir tank whose interior is in communication with the passage, the tank including a cylindrical portion coaxially surrounding the capillary tube and axial end portions via which the tube is connected to the tank in a manner to seal the interior of the tank, a mass of active laser gas filling the interior of the reservoir tank and the capillary passage, a cathode disposed in the interior of the tank, a counterelectrode in communication with the capillary passage, and optical elements sealing the ends of the capillary passage, the capillary tube is symmetrical with respect to a plane perpendicular to the axis of the capillary passage and midway between the ends thereof, the counterelectrode is composed of two anodes each disposed at a respective axial end of the capillary tube, communication between the capillary passage and the interior of the tank is provided by an opening passing through the capillary tube, and a radially stiff, axially mobile mechanical connection is provided between at least one portion of the capillary tube at at least one portion of the tank.
