This patent describes a gas laser tube comprising: (a) axially aligned, elongated, thin wall cylindrical segments of electrically insulating material successively disposed between electrodes at anode and cathode ends in hermetically bonded relationship with one another and forming an outer wall the laser tube, each cylinder segment defining within the wall thereof a longitudinally extending cylindrical cavity; (b) a pair of thin metallic support members mounted within each cavity of each segment, each support member having an outer peripheral portion bonded to the inner wall surface of the segment in which it is mounted and an inner portion defining with the inner portion of the other support member of the pair an axial aperture aligned with axial apertures of other pairs of support members, each support member having a gas path return hold axially offset from the axial aperture and also offset from one support member of the pair to the other in the direction of gas return travel, each pair of the support members providing a metallic channel forming gas communicating space and a torturous between the gas returning holes of the pair; (c) a ferrule within each cavity of each segment located within and secured to the inner portions of the pair of support members within the cavity.
