Paper Abstract

Pulsed discharge is effective means to achieve high-peak lasing in COIL. Numerical model is developed for simulation of pulsed discharge in gas stream from the singlet oxygen generator mixed with CF3I. The model comprises a system of kinetic equations for neutral and charged species, electric circuit equation, and gas thermal balance equation. Sources of iodine atoms under discharge and post-discharge conditions are analyzed. The dominant source in the discharge is electron-impact dissociation of CF3I molecules. In post-discharge phase chemical reactions are identified giving notable input into I production. Deformation of laser pulse waveform observed experimentally is explained by influence of these reactions.
