Abstract

Experiments^[1] with Electric Oxygen-Iodine Laser (ElectricOIL) heat exchanger technology have demonstrated improved control of oxygen atom density and thermal energy, with minimal quenching of O₂(a¹Δ), and increasing small signal gain from 0.26% cm^-1 to 0.30% cm^-1. Heat exchanger technological improvements were achieved through both experimental and modeling studies, including estimation of O₂(a¹Δ) surface quenching coefficients for select ElectricOIL materials downstream of a radio-frequency discharge-driven singlet oxygen generator. Estimation of O₂(a¹Δ) quenching coefficients is differentiated from previous studies by inclusion of oxygen atoms, historically scrubbed using HgO^[2-4] or AgO^[5]. High-fidelity, time-dependent and steady-state simulations are presented using the new BLAZE-VI multi-physics simulation suite^[6] and compared to data.
