Pulsed laser electrode assembly
An electrode assembly for a compact high vacuum pulsed gas discharge laser comprises an elongated cathode and a coextensive anode spaced apart in a direction transversely of the flow of gas to define a discharge gap. Each of the electrodes is connected at a plurality of equally spaced points along its length to a like number of conductive rods which extend through the top wall of the laser housing for connection to a power source. The cathode comprises a carrier bar directly attached to said rods and a cathode bar adjustably secured to the carrier bar for vertical movement toward and away from the anode to permit attainment of a uniform discharge gap throughout the length of the electrodes. Preionization of the discharge gap is achieved by means of a conductive sleeve electrically connected to one of the electrodes and disposed against the inner surface of a dielectric tube which contacts the other electrode throughout its length. A cooling tube from an external source of coolant passes through a vacuumtight housing feedthrough post for engagement with the cathode carrier bar over its length for cooling the cathode assembly.
