Abstract

Abstract

From the theory of uniform-field electrodes, profiles of electrodes, theoretical and practical distributions of electric field on the surface of near Rogowski electrode, Chang electrode (including compact Chang electrode) and Ernst electrode were calculated and discussed. Using these electrodes in our laboratory, pulsed discharge experiments were carried out on TEA CO2 laser, so discharge performance and output characteristics were obtained, and the results of the experiments on these electrodes were compared and analyzed. The calculation results show that Ernst electrode has the most compact profile and optimal uniform electric-field distribution if electrodes have the same fundamental parameters. The experiment results indicate that TEA CO2 laser gains the biggest glow discharge area and
