The demonstration and characterization of a multiwatt all gas-phase iodine laser (AGIL) are described. A 20-cm subsonic reactor was used to produce NCl (a1Δ) for series parametric studies of the I*(2P12/)-I(2P32/) small-signal gain and extracted power dependence on reactant flow rates and reaction time. The highest measured gain was 2.5×10-4 cm-1 and the highest power observed was 15 W.
