Abstract

Herein the authors report on the demonstration of a 50% enhancement in gain and 38% enhancement in continuous-wave laser power on the 1315 nm transition of atomic iodine through the addition of a secondary discharge to predissociate the molecular iodine in an electric oxygen-iodine laser. In the primary discharge the O2 (a Δ1) is produced by a radio-frequency-excited electric discharge sustained in an O2 -He-NO gas mixture, and I (P 12 2) is then pumped using energy transferred from O2 (a Δ1). A gain of 0.10% cm-1 was obtained and the total laser output power was 6.2 W.
