Abstract

Experiments and modeling have led to continued enhancements in the Electric Oxygen-Iodine Laser (ElectricOIL) system. This continuous wave (cw) laser operating on the 1315 nm transition of atomic iodine is pumped by the production of O2(a) in a radio-frequency (RF) discharge in an O 2/He/NO gas mixture. New discharge geometries and increases in gain length, flow rates, discharge power, and resonator mode volume have improved the peak measured gain to 0.26% cm-1 and the outcoupled laser power to 102 W. The BLAZE model has been used to perform end-to-end (discharge though laser resonator) simulations of the new system configuration to help guide this process. Results are in good agreement with data. Additional measurements of gain recovery downstream of an operating laser cavity for five cases of interest are presented and modeled. The deviation of the gain recovery data from calculations based on presently accepted theory is highlighted. Several potential mechanisms to explain this theory are presented and discussed.
