PURPOSE:To allow long time operation by constituting discharge electrode for pulsed gas laser of an actual polar discharge electrode and an electrode for shaping the field distribution specifically. CONSTITUTION:The discharge electrode for pulse gas laser comprises a polar discharge electrode 1 having actually discharging surface profile forming a part of churn profile with screw gears being provided on the opposite sides thereof, a field shaping electrode 2 forming the surface churn profile along with the surface profile of the polar discharge electrode 1, and means for rotating the polar discharge electrode 1, i.e., a screw 5, having a screw gear at the tip thereof mating with screw gears provided on the opposite sides of the polar discharge electrode 1. Pulse current is transmitted from an external pumping circuit through a current introducing rod 3 and an electrode position adjusting screw 4 coupled therewith to the discharge electrode. The polar discharge electrode 1 has four discharging faces shifted by 90 deg. in angle and provides churn profile along with the discharge face of the field shaping electrode 2. |
