This paper presents measurements of spectrally and temporally resolved laser-induced incandescence (LII) from soot. The second harmonic (532 nm) from a nanosecond Nd:YAG laser was used to heat the soot over a wide range of fluences. The emission was spectrally resolved using a spectrograph attached to an intensified CCD camera with a gate width of 1.5 ns. At fluences below 0.2 J/cm2, corresponding to the sublimation threshold, spectra demonstrate broadband featureless emission characteristic of laser-induced incandescence, whereas at higher fluences spectra show sharp features attributable to C2 Swan band emission, C3 Swings band emission, and other species. These features perturb the LII signal at wavelengths between 380 and 680 nm, suggesting that this detection region should be avoided for LII measurements made using a 532-nm laser beam at fluences of 0.2 J/cm2 and above. The detection wavelength regions to be avoided are much more extensive than previously believed.
