Abstract

Microwave discharge of a Cl 2 He mixture as a simple, clean and efficient Cl atom generator was used for an all gas-phase iodine laser study. Sufficient NCl ( a 1 Δ ) was produced through the reaction of HN 3 + 2 Cl NCl ( a 1 Δ ) + HCl + N 2 . The energy transfer reaction of I ( P 3 2 2 ) + NCl ( a 1 Δ ) I ( P 1 2 2 ) + NCl ( X 3 Σ ) was observed. A population inversion was observed directly by using a 1315 nm tunable diode laser by scanning the entire line shape of the (3,4) hyperfine transition of iodine, and a small signal gain of 5 × 10 - 5 cm - 1 was obtained.
