| Abstract: | Remote filament-induced fluorescence spectroscopy is used to probe a cloud of smoke, produced from burning mosquito coils, located at a distance of 25 m from the laser source and LIDAR detector. CN, CH and C2 molecular fragments were identified in the sample. We demonstrate that temporally gated measurement is an efficient technique to easily suppress spectral contaminations, such as white light and atmospheric N2 fluorescence. |
