Abstract
An improved electrode configuration and method for the deposition of electrical power into an electric discharge laser having a gas path transversely disposed to an optical axis and the electric field is disclosed. The electrode configuration includes a cathode, having one or more common geometry rod elements of a thoriated material disposed transverse to a gas path and a planar anode disposed opposite the cathode in a parallel relationship thereto wherein the cathode and the anode define the gas path therebetween. The electrode configuration is adapted for operation without ballast resistance in the electrical circuit and without the utilization of preionization means. The electrode configuration provides a discharge having substantially diffuse and uniform characteristics within the discharge region.
