Abstract

Numerical modeling of gas, pulsed, UV preionized Transversely Excited Atmospheric (TEA) carbon-dioxide laser has been considered. The modeling is carried out for case of a specific electrical circuit of TEA CO2 system operating with CO2/N2/He and CO2/N2/H2 gas mixture. Proposed model represents the time evolution of voltage, current and electron concentration on a satisfied manner in inter-electrode laser space. Agreement between theory and experiment is quite good. Simulated values of voltage and current are of short duration which in a manner affects the optical, i.e. laser pulse.
