Development and Performance Characteristics of a UV-Preionized, High-Power TEA Pulsed CO2-Laser
Abstract
This paper presents a series of systematic studies on a UV-preionized, high-power TEA pulsed CO2-laser with a total laser output energy exceeding 300 joules, a peak output power of GW level and a duration of the first spike of about 50 ns. The studies include (1) the preionization characteristics under UV-irradiation generated by an intense arc-discharge-gap assembly, (2) the main laser discharge characteristics in combination with the UV-preionizing scheme, (3) the optimum relative concentration of the laser gas mixture for maximum peak value of the small-signal gain, and (4) the laser oscillation characteristics using appropriate optical resonator systems which maximize the laser output energy contained in the first spike.
