Abstract

Abstract: The output characteristics of a home-made 1–3 atm pulsed CO2 laser are simulated by using Six-Temperature Vibrational-Rotational Dynamic Model (6TVRM). The discharge volume was modeled by a non-linear distributed lumped electric circuit and the electron density was calculated by Transmission Line Method. Different characteristics of the laser pulses such as energy, build-up time and duration of the spike and tail parts were measured at various operational conditions of the pressure, discharge voltage and main capacitance. Then, the obtained data were compared with the simulation results calculated for the corresponding conditions. The good agreement observed between the experimental and simulation results has revealed the promising capability of 6TVRM to be generalized for describing the output behavior of the supper-atmospheric pulsed CO2 lasers.
