摘要：

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. O(2)(a (1)Delta) is produced by a single radio-frequency-excited electric discharge sustained in an O(2)-He-NO gas mixture flowing through a rectangular geometry, and I((2)P(1/2)) is then pumped using energy transferred from O(2)(a (1)Delta). A gain of 0.26% cm(-1) was obtained and the total laser output power was 54.8 W.
