Paper Abstract

In an electric discharge Oxygen-Iodine laser (ElectricOIL), the desired O2(a1Δ) is produced using a low-to-medium pressure electric discharge. The discharge production of atomic oxygen, ozone, and other excited species adds higher levels of complexity to the post-discharge kinetics which are not encountered in a classic purely chemical O2(a1-Δ) generation system. Mixing effects are also present. In this paper we present post-discharge modeling results obtained using a modified version of the Blaze-II gas laser code. A 28 specie, 105 reaction chemical kinetic reaction set for the post-discharge kinetics is presented. Calculations were performed to ascertain the impact of a two stream mixing mechanism on the numerical model and to study gain as a function of reactant mass flow rates. The calculations were compared with experimental data. Agreement with experimental data was improved with the addition of new kinetics and the mixing mechanism.
