Parametric studies of uv preionization in TEA CO2 laser

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.
