Abstract
A pulse oscillating gas laser device, which can reduce an influence of a shock wave caused by primary discharge and perform stable laser oscillation is provided. To this end, the device is a pulse oscillating gas laser device for exciting a laser gas by causing primary discharge in a pulse form between a pair of discharge electrodes ( ) opposing each other and oscillating laser light, in which a rib portion ( ) with insulating properties for preventing creeping discharge is provided on a cathode base ( ) with insulating properties, to which the discharge electrode ( ) at a high voltage side is fixed, and a damping material ( ) for attenuating a shock wave ( ) caused by the primary discharge is inserted in an inside of a groove portion ( ) between a raised portion ( ) of the rib portion ( ) and the high-voltage side discharge electrode ( ).
