Abstract
A gas laser tube assembly is disclosed wherein an elongated gas laser plasma tube is connected by a releasable connection to a member having a gas port positioned adjacent one end of the elongated gas laser plasma tube in spaced relationship thereto along the longitudinal axis of the plasma tube. The releasable connection and the member are arranged for telescoping movement with respect to another in either direction along the longitudinal axis of the plasma tube at least upon release of the connection thereby facilitating removal and installation of the plasma tube from the assembly. The releasable connection includes a first part connected to one end of the plasma tube and a second part releasably connected to the member with the first and second parts being releasably connected to one another. A cooling jacket surrounding the plasma tube is connected at one of its ends to the first part and an electrode is mounted on the second part and extends within the one end of the plasma tube whereby the electrode can be removed from the assembly for cleaning, repair or replacement without disturbing the integrity of the coolant passage defined between the cooling jacket and the plasma tub…
