ABSTRACT:
The gas laser of this invention includes a discharge tube formed from a plurality of metallic bodies arranged in end to end alignment. The tube is terminated by a cathode chamber at one end and an anode chamber at the other end. Each of the metallic bodies and the cathode and anode chambers is provided at least with one tubular element said elements being joined together by means of a glass welding bead. The material forming said tubular elements has the same coefficient of thermal expansion as glass. The invention finds particular application to completely sealed lasers.
