Oxygen atom density and thermal energy control in an electric-oxygen iodine laser

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 O-2(a(1)Delta), 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 O-2(a(1)Delta) surface quenching coefficients for select ElectricOIL materials downstream of a radio-frequency discharge-driven singlet oxygen generator. Estimation of O-2(a(1)Delta) 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.
