  • Closed cycle annular-return gas flow electrical discharge laser
    Patent number: 4274065
    Abstract: A closed cycle, high repetition pulsed laser having a laser flow channel with an annular flow return surrounding the laser flow channel. Ultra high vacuum components and low out-gassing materials are used in the device. An externally driven axial flow fan is used for gas recirculation. A thyratron-switched low-inductance energy storage capacitor is used to provide a transverse discharge between profiled electrodes in the laser cavity.
