Abstract
An electrically pumped gas laser with an electrode assembly providing for gas flow through spaced upstream and downstream electrode arrays with the flow path perpendicular to the optical axis of the laser in a very low inductance electrical circuit. Electrode arrays comprising parallel spaced blade shaped electrodes, with the upstream electrodes having a contoured leading edge and a trailing knife edge spaced from the walls of the discharge space, and with the downstream electrodes having a leading knife edge spaced from the walls of the discharge space and a similarly contoured trailing edge. An electrode assembly with upstream and downstream gas flow channels providing a double parallel plate transmission line for electrical connections and energy storage, with the channel walls serving either directly or as supporting structures for the inner plates, and with the outer plates in the form of conducting sheets spaced from the inner plates by insulating sheets.
