Abstract

PURPOSE:To prevent local overheating by dispersing a glow discharge with an insulator interposed between a discharge tube end and an anode. CONSTITUTION:An insulating cylinder 20 is provided on the discharging surface of an anode adjacent to a discharge tube end 11A in such a manner as to be flush with the surface. The discharge tube end 11A, the insulating cylinder 20 and the discharging surface 17 of the electrode are arranged in that order. Driven by a gas stream, a glow discharge 14 spreads over the entire discharging surface of the anode without concentration. As a result, a discharge input can be applied stably and as the inner diameter of the discharging surface 17 is larger than that of the discharge tube 11, the glow discharge spreads over the entire area in the discharge tube thereby effectively exciting a laser gas therein.
