ABSTRACT:
A cathode assembly for a gas laser housing has weldless sleeves for securing a cathode to the laser housing. A support flange, brazed or heliarc welded to a gas reservoir at one end of a laser tube, supports a cathode. Ceramic feedthroughs brazed or heliarc welded to holes in the flange bring wires through the flange while maintaining insulation therefrom. The helical cathode is joined to copper stubs from the feedthroughs by crimped conductive sleeves.
