An electrically excited gas laser having a dual-purpose electrode configuration. Two long parallel metal electrodes on opposite sides of the gas volume are almost totally enclosed in a dielectric body material. A raised projection of each electrode, at opposite body ends, is in direct contact with the laser gas. A conventional pulse generator is connected to the electrodes. When a pump pulse is applied, a transverse glow discharge is initiated which rapidly gives way to a main longitudinal discharge. In an alternate arrangement, the electrodes comprise several discharge sections in series along the laser body, connected in electrical parallel to the pulse generator.
