ABSTRACT:
An electrode assembly and a D.C. glow discharge system incorporating the electrode assembly. The system is stabilized by a lower pulse repetition rate (1 KHz-5 KHz) and power (<5% of sustainer power) than that required for pulse-sustained discharge. It operates with a self-sustained discharge at lower voltage than usual due to lowered work functions, increased secondary emission and effective ionization. The pulse-stabilized discharged provides an extended stable operation suitable for high power gas lasers. A water ballasted electrode unit used therein, having individually ballasted electrode elements with discrete water resistors so formed when water flows, eliminates temporally varying spatial current fluctuations and exhibits such unique characteristics as; providing capacitive coupling for a pulse, and resistive coupling for D.C., and self-optimizing current uniformity with the operating time. The electrode unit includes electrode elements protruding into the discharge volume, enlarging the effective diameter of the electrode elements resulting in a uniform discharge. The electrode unit configuration provides a positive means for removing heat from the cathode fall region, and an economical and efficient means of manufacturing. The electrode unit structural configuration is particularly well suited for a pulse-stabilized glow discharge system and can be scaled up by a building block concept to produce super high power gas lasers. High power laser system employing the discharge principle and electrode units may be referred to as a S.O.A.P. (Self-Optimizing, Abnormal-glow, Pulse-stabilized) laser.
