OSTI ID:7006049
This patent describes an ion laser. It comprises: a substantially cylindrical ceramic tube including an interior step, a plurality of thin metal disc each having a central aperture defining a plasma discharge region extending substantially along a longitudinal axis of the tube, and a plurality of apertures disposed substantially at the periphery of each disc to allow for equalization of pressure within the interior of the tube; an annulus of ceramic formed around the periphery of each individual disc forming a metal disk member the disc being stacked in the interior of the tube and being supported by the step. The annulus of ceramic supporting each of the disc members in the ceramic tube and the ceramic annulus and providing heat transport from the thin metal disc to the ceramic tube to provide cooling of the plasma discharge region; a cathode disposed in the interior of the ceramic tube; an anode disposed in the interior of the ceramic tube; means for hermetically sealing each opposing end of the tube; and mirror means disposed at each opposing end of the tube.
