Abstract
An extruded aluminum gas laser tube assembly (10) has a pair of extruded, elongated, electrically insulated, aluminum electrodes (23,24) adapted to couple to an external RF supply and supported in the laser tube in predetermined spaced-apart relationship relative to each other and to the laser tube (11). The electrode supporting structure is eight pairs of matching, longitudinal, machined grooves (12,21), four pairs at each end of the tube (11) and electrodes (23,24) in each of which pairs is received a cylindrical, insulated, anodized aluminum spacer pin (22) which slidably supports the electrodes in the tube and allows longitudinal expansion of the electrodes relative to the tube substantially without bending.
