Abstract

Recent experiments have led to improvements in the hybrid Electric Oxygen-Iodine Laser (ElectricOIL) system that significantly increased the laser power output. The continuous wave laser operating on the I(2P 1/2) → I(2P3/2) transition of atomic iodine at 1315 nm was pumped by the production of O2(a 1Δ) in a radio-frequency discharge in a He/O2 mixture. Molecular iodine was injected into the flow products 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. The outcoupled laser power was used as a diagnostic to analyze the global effects of pressure, primary/secondary flow rates, sensitizer gases, discharge configuration and other system parameters.
