Abstract

In this paper, we report on studies of a continuous-wave laser at 1315 nm on the I(²P_1/2) → I(² P_3/2) transition of atomic iodine where the O₂ (a¹ Δ) used to pump the iodine was produced by a radio frequency excited electric discharge. The electric discharge was sustained in He-O₂ and Ar-O₂ 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, discharge arrangements, and mirror sets are presented. The highest laser output power obtained in these experiments was 520 mW in a stable cavity composed of two 99.995% reflective mirrors.
