title = "Measurement of positive gain on the 1315 nm transition of atomic iodine pumped by O 2(a 1 Δ) produced in an electric discharge",
abstract = "The measurement of positive gain on the I( 2P 1/2) →I( 2P 3/2) electronic transition of the iodine (I) atom at 1315 nm pumped by resonant excitation transfer from O 2( 1δ) produced in an electric discharge was investigated. The electric discharge was followed by continuously flowing supersonic cavity to lower the flow temperature and reduce the backward pumping. This produced required population inversion to observe the small, but easily identified positive gain of approximately 0.002% cm -1. The measurements of gain were enabled by tunable diode laser which was capable of scanning the entire line shape of the (3,4)hyperfine transition of Iodine.",
