Abstract
A numerical model for the discharge processes of a UV-preionized transversely excited atmospheric pressure (TEA) CO2 laser is presented,in which the discharge circuit and the discharge area are considered in detail,and the temporal evolution of discharge voltage,current and electron density are given.Comparisons of the simulation results with the related experimental results are presented together with discussions of the factors affecting the stability of gas discharge in the laser.
