Abstract

Recent experiments have led to improvements in the hybrid Electric Oxygen-Iodine Laser (ElectricOIL) system that significantly increased the discharge performance, supersonic cavity gain, and laser power output. The continuous wave laser operating on the I(2P1/2) → I(2P3/2) transition of atomic iodine at 1315 nm was pumped by the production of O2(a1Δ) in a radio-frequency discharge in an O2/He/NO gas mixture. Molecular iodine was injected into the active oxygen flow from the electric discharge and expanded through a supersonic cavity to lower the gas mixture temperature and shift the atomic iodine equilibrium in favor of the I(2P1/2) state. Greater than 30% of the discharge power is now being coupled into the active oxygen gas flow, a gain of 0.067% cm-1, and a laser power of 4.5 Watts were measured. Modeling with the BLAZE-IV model is in good agreement with data.
