ABSTRACT:
In a gas laser having a capillary and a cathode that envelopes the capillary, a fastening of the cathode suitable for batch soldering is achieved in that the cathode is secured to an end piece having a mount for an optical element, and an end of the cathode facing away from the end piece is elastically supported against a housing wall with such a slight spring power that a weight of the unit formed of the cathode, end piece, and mount is adequate for overcoming the friction between the spring and the housing wall. Thus, the end piece with the attached cathode can slide into its final position during soldering solely on the basis of the force of gravity. The invention is particularly suited for helium-neon lasers that are manufactured in glass solder technology.
