title = "Enhancement of FLEET in argon gas mixtures",
abstract = "Argon gas is demonstrated to enhance Femtosecond Laser Electronic Excitation Tagging (FLEET) in atmospheric pressure and temperature conditions. Significant improvement in FLEET line characteristics has been experimentally observed with the addition of argon gas to nitrogen-containing flows. Spectra and images of the resulting tagged line provide insight into the effects of argon on the FLEET process. Spectroscopic measurements of the tagged line in nitrogen-argon gas mixtures at different times following excitation en-able determination of the temporal evolution of atomic and molecular participants in the reactions. Enhancement of the nitrogen first positive and second positive systems within the first microsecond of tagging is observed with increasing ratios of argon to nitrogen gas. Additionally, long-lived ionization-recombination reactions following femtosecond laser dis-sociation in pure argon creates fluorescence that can be harnessed for tagging in argon flows. A kinetic model is developed for comparison with experimental data to corroborate the key mechanisms responsible for these observations.",
