Abstract
A plurality of spaced-apart apertured discs constructed of electrical insulator material, are sealed within the quartz tube structure of a metal halide laser tube to increase the path length along the wall of the laser tube between the discharged electrodes to constrain the discharge to the central gaseous core rather than along the wall of the quartz tube. The use of electrical insulator apertured discs sealed with the laser tube of a metal halide laser facilitates the utilization of the halide species as the laser medium.
