Abstract

We measure the backward fluorescence spectra generated by the femtosecond filament transmitting through the butane/air flame, and study the fluorescence emission from combustion intermediates (CN, CH and C₂ radicals), air (mainly N₂ and N₂⁺). It is found that the fluorescence emission from combustion intermediates, N₂ and N₂⁺ shows difference when the femtosecond filament transmits through different parts of the butane/air flame, and we attempt to analyze it in this paper. This study demonstrates that the filament-induced fluorescence technique can be utilized to sense the combustion intermediates.

Keywords: Combustion; Femtosecond filament; Fluorescence; Remote sensing.
