Corona preionization technique for carbon dioxide TEA lasers
Abstract
An experimental program is reported which investigates the basic physics underlying the surface corona preionization process in CO2 TEA lasers. Measurements were made of UV emission spectra, photoelectron density, current and voltage waveforms and laser output for a matrix of physical parameters known to influence corona preionization. Based upon experimental results, guidelines are given for the design of a corona preionized CO2 TEA laser.
