This patent describes a gas laser. The laser includes: a laser cavity, mirror means defining an optical path in the cavity, electrodes defining an electric discharge path in the cavity, the electrodes including at least one tubular anode member having a passage therethrough which at one end opens into the cavity; gas supply means for injecting gas into the cavity through the passage, an electrically conducting anode surface provided across the passage and recessed within the tubular member, the surface being perforated to allow gas to pass therethrough, and insulating means surrounding the electrically conducting anode surface to prevent travel of a root of the discharge away from the anode surface means.
