Picosecond- and nanosecond-duration laser pulses are used for two-photon-resonant laser-induced fluorescence detection of atomic hydrogen in methane and hydrogen flames At high laser fluence, measurements are corrupted by interference from photolytic generation of atomic hydrogen from other flame constituents and/or stimulated emission (SE). For many flames, excitation with picosecond pulses produces significantly larger interference-free signal because of reduced photodissociation, but the optimum laser pulse width generally depends on the flame composition and geometry. For further details, see the paper by Kulatilaka et al., pp. 4672-4683.(Graphics design by Daniel L. Strong, Sandia National Laboratories.)
