ABSTRACT:
A structure for holding tubular cathode in a gas laser tube. The cathode is provided at one end with a slender projection inserted into a hollow member attached to one sealing flush member and caulked at a groove formed in the hollow member to hold the cathode. The cathode is also provided with spring plate members at the other end. A slender discharge tube is provided with an expanded portion serving as a discharge chamber, the expanded portion having a smaller diameter than the cathode and pressing against the spring plate members. The spring plate members securely hold the cathode within the gas laser tube without melting or cracking at the sealing flush members during welding.
