Abstract :
Gain is measured on the electronic I(2P3/2)–I∗(2P1/2) transition of atomic iodine at 1.315 μm 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∗(2P1/2) atoms from the efficient energy transfer reaction between NCl(a 1Δ) metastable and ground state I(2P3/2) atoms. The population inversion was directly observed using a 1.315 μm tunable diode laser that scanned the entire line shape of the (3,4) hyperfine transition of iodine.
