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.
