Remote filament-induced fluorescence spectroscopy from thin clouds of smoke

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 C 2 molecular fragments were identified in the sample. We demonstrate that temporally gated me...

More Information
Summary: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 C 2 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 N 2 fluorescence.
