Abstract
A laser includes a discharge tube formed from one piece and penetrating, with play, into an anode chamber on one side and into a cathode chamber on the other side, the anode and cathode chambers having a thermal expansion coefficient different from that of the discharge tube. Bellows are hermetically welded by their first ends to the anode and sealed by a glass bead to the discharge tube at their second ends.
