IMPROVED METAL VAPOR LASER DISCHARGE TUBE ABSTRACT OF THE DISCLOSURE An internal mirror metal vapor laser, and in particular, a helium-cadmium laser discharge tube, which is economical, compact and has a relatively long op- erating and shelf life, the operating life typically exceeding 10,000 hours. A positive column helium-cadmium laser tube of the consumable type and having optical resonator mirrors integral with the tube ends to hermetically seal the tube is provided which includes a relatively large volume cadmium reservoir capable of containing sufficient cadmium for operating life times exceeding ten thousand hours. A heater is applied to the cadmium reservoir for controlling the cadmium vapor pressure. The helium pressure is actively controlled by releasing helium from a high pressure helium reservoir when the helium pressure is less than a predetermined value. This is ac- complished by providing a signal representing the sensed pressure of the helium in the laser discharge tube and comparing electronically this signal with a signal representing the pressure of helium at a desired operating condition (reference pressure).
