Enhancement of electric oxygen-iodine laser performance using a rectangular discharge and longer gain length

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 ~1Δ) 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(~2P_(1/2)) is then pumped using energy transferred from O_2(a ~1Δ). A gain of 0.26% cm~(-1) was obtained and the total laser output power was 54.8 W.
