Abstract
A gas laser having a vacuum-tight discharge tube characterized by the discharge tube consisting of a glass cylinder whose two ends are closed by metal caps. Each of the metal caps support a mirror member which is connected to a transition member by a glass solder connection. A laser capillary which is made of glass has one end fused to the glass cylinder and has its other end supported by a spring which consists of a material which has a high heat resistance and may be hardened after assembly with the laser capillary and discharge tube. The laser capillary has a portion surrounded by a cold cathode which is disposed in the interior of the discharge tube and consists of a rolled sheet of resilient metal which tightly engages the inner surface of the discharge tube due to its own resilient spring force.
