Abstract :
We demonstrated a femtosecond pulse driven electron-impact method to efficiently enhance the intensity of filament-induced neon and helium fluorescence emission. Such an all-optical method holds the potential applications to improve the sensitivity of laser-induced breakdown spectroscopy.
