Abstract

PURPOSE:To contrive the high speed of discharging pulse glow and to reduce the withstand voltage of a switching circuit in the gas laser device by retaining continuous glow discharge with an electric input less than threshold and executing pulse glow discharge as superimposed with this glow discharge. CONSTITUTION:An anode 7, a cathode 8 and trigger electrode 10 are contained in a laser tube 1 filled with laser medium therein. A power supply circuit having a DC high voltage power supply 4, a switching circuit 5 and a discharge stabilizing ballast resistor 6 connected in series with each other is connected between the anode 7 and the cathode 8, the power supply 4 and the circuit 4 are operated, and a voltage is applied between the anode 7 and the cathode 8, and a glow discharge is generated between the cathode 8 and the electrode 10. Then, a glow discharge is generated between the anode 7 and the cathode 8 by the discharge trigger operation, the laser tube 1 is excited therein, and the laser light 11 is irradiated through a concave reflecting mirror 2 and a plane output mirror 3. The circuit 5 is operated in this operation, a pulse glow discharge 13 is executed as superimposed with the continuous glow discharge 12, and the withstand voltage of the circuit 5 is reduced.
