ABSTRACT:
A gas laser discharge tube comprises a discharge vessel containing a discharge gas, a rod-shaped anode, a corrugated cathode and a voltage source connected between the anode and cathode. The corrugated cathode comprises a metal hollow cylinder arranged coaxially with the optical axis of the laser and a plurality of metal discs arranged coaxially with the optical axis of the laser at regular intervals in the axial direction of the metal hollow cylinder. The discs have their peripheries secured to the inner periphery of the metal hollow cylinder. Each disc has a central hole and another hole through which the anode extends parallel to the optical axis of the laser.
