In this paper we report on studies of a continuous wave laser at 1315 nm on the I( 2P 1/2) → I( 2P 3/2) transition of atomic iodine where the O 2(a 1Δ) used to pump the iodine was produced by a radio frequency excited electric discharge. The electric discharge was sustained in He/O 2 gas mixtures upstream of a supersonic cavity which is employed to lower the temperature of the continuous gas flow and shift the equilibrium of atomic iodine in favor of the I( 2P 1/2) state. The results of experimental studies for several different flow conditions and mirror sets are presented. The highest laser output power obtained in these experiments was 510 mW in a stable cavity composed of two 99.993% reflective mirrors. Blaze II laser model was used to model typical ElectricOIL conditions in the post-discharge region through the laser cavity. Overall the Blaze II simulation model appears to be predicting many of the observed qualitative trends that have been measured and the quantitative comparisons to data are reasonable.
