1. A gas laser system comprising a laser tube with two rectangular substantially flat electrodes positioned opposite one another and parallel to the axis of the tube for producing a substantially uniform field, a direct current source with a buffer capacitor connected in parallel therewith, one terminal of said current source being connected to the first of said electrodes, and means for inducing the ionization of the gas preceding the discharge in the gas mixture, said means comprising at least one metal plate connected to the other terminal of the source of current and being insulated at the side of the discharge and being positioned in parallel to the axis between parallel running edges of the electrodes, a series connection of an impedance and an inductor mutually connecting the electrodes, said inductor connectd to said second electrode, a switch which may temporarily connect the junction of the impedance and the inductor to the metal plate, and a capacitor connected between the second electrode and the metal plate.
