Claims

[Claims for Utility Model Registration] (1) A support assembly consisting of a metal support for supporting an optical resonator mirror and a metal enclosure plate fixed to the support is provided at both ends of the glass bulb. , has a glass capillary tube whose one end is joined to the anode side of the glass bulb inside the tube sealed in the glass bulb, and a cylindrical cathode that surrounds the glass capillary tube and is held close to the inner surface of the glass bulb. In the gas laser tube, a spring holding the end of the cathode against the glass bulb with a spring property is bent in a zigzag manner in the axial direction of the cathode, and is arranged at the periphery of the spring, which is bent in a zigzag manner in the axial direction of the cathode. The arms are arranged alternately in two types, one with the tip bent outward with respect to the cathode and the other with the tip bent inward, and the cathode is arranged in two different types. A gas laser tube characterized in that it is held from both sides by the arms of the gas laser tube. (2) Registration of a utility model characterized in that the portion of the spring set forth in item 1 above that engages with the cathode end surface is the entire surface of the cathode end surface, and a bent portion for holding the glass tube is formed in the center thereof. A gas laser tube according to claim 1.
