Abstract
Plasma tube for gas lasers including an elongate cylindrical glass envelope closed at one end with a conductive metal anode disc and at the other with a metal cathode disc, each of which has been intimately fused with the envelope. The envelope carries an internally mounted capillary having a bore for confining a discharge within the tube, the capillary being supported by a flange member connected between the capillary and the envelope. Each disc has a centrally located aperture which is aligned with the capillary bore, each aperture being closed by a suitable reflector for defining an optical cavity. Fine tuning of the cavity is accomplished by incremental deformation of one or both of the discs.
