Abstract
The discharge characteristics of an electrical circuit for uv preionization in TEA CO2 laser are described. The suitable size of an electrode for uniform volumetric preionization of a laser gas is decided. The mechanisms of the ionization and the generated total initial electrons by uv photons are discussed. Moreover, both the effects of circuit parameters R, L on the intensity of uv radiation and the endurance test of the electrode for repeated discharges are also described.
