The Measurement of Gain on the 1.315 Micrometers Transition of Atomic Iodine in a Subsonic Flow of Chemically Generated NCl(a(1) delta)

Abstract

Gain is measured on the electronic I - I(*) transition of atomic iodine at 1.315 microns when hydrazoic acid (HN3) is injected into a flow of iodine and chlorine atoms. The inversion was generated in a transverse subsonic flow device that produced electronically excited I(*) atoms from the efficient energy transfer reaction between NCl(a) metastable and ground state I atoms. The population inversion was directly observed using a 1.315 micron tunable diode laser that scanned the entire line shape of the (3, 4) hyperfine transition of iodine.
