The collisional kinetics of upper state formation for the iodine monofluoride (IF) discharge pumped laser have been studied using tunable dye laser absorption spectroscopy. As for electron- beam excitation, the immediate precursor to IF*(D′) is found to be the I*(6s4P) species. Energy stored in the F*(4P) states, however, is not recovered in the laser's output due to weak F*→I* collisional coupling. Limited tunability of this laser has been demonstrated with a Littrow prism and has resulted in the observation of a new D′→A′laser transition at 467 nm.
