Abstract

Herein the authors report on the demonstration of a 95% enhancement in continuous-wave laser power on the 1315 nm transition of atomic iodine via a 50% increase in gain length, flow rates, and discharge power. O₂ (a Δ¹) is produced by a single radio-frequency-excited electric discharge sustained in an O₂ -He-NO gas mixture flowing through a rectangular geometry, and I (P² _1/2) is then pumped using energy transferred from O₂ (a Δ¹). A gain of 0.26% cm^-1 was obtained and the total laser output power was 54.8 W.
