“…As such, the first excited state of the NCl molecule, NCl(a 1 ) is metastable and capable of transferring it's energy to the iodine atom as does O 2 ( 1 ) in the chemical oxygen iodine laser. Lasers have been demonstrated using the energy transfer from NCl(a 1 ) to iodine atoms [1,2]. These lasers produce NCl(a 1 ) from the reaction of chlorine atoms and hydrogen azide.…”

The NCl-I laser has been demonstrated using HN 3 as a fuel with a combustor to produce chlorine atoms. In this paper, we study the auto-decomposition of NCl 3 . This process could result in a new type of chemical laser that would not need a combustor. We present the results of experiments designed to understand the basic physical processes in this system. The NCl-I laser operates using only gaseous species, eliminating the need for heterogeneous gas liquid reactions such as used in COIL chemical lasers. The lasing species is the same as in COIL, simplifying the scaling process since many optical, tracking and propagation problems have been demonstrated in the ABL program.
