Abstract
Abstract A gas laser having both a discharge tube with a capillary tube and an electronic arrangement, which serves as a power supply, sealed in a housing characterized by the housing being a metal tube having each end closed by an end wall to form a sealed chamber which contains the electronic arrangement which is a hollow cylinder that concentrically receives the capillary tube. Preferably, the chamber of the housing is filled with an electrically insulating and heat conducting material which is either a liquid or cast therein. The electronic arrangement preferably comprises the elements of the arrangement embedded in a cast plastic material which is cast in a hollow cylinder. One of the end walls of the housing contains the decoupling window and has a conical recess therearound for receiving a free end of the capillary tube which is sealed by an O-ring sealing ring and which is urged into engagement with the conical recess by a spring plate disposed in the housing.
