From: Transition of Femtosecond-Filament-Solid Interactions from Single to Multiple Filament Regime
Normalized central axis emission from target species. Time-resolved, normalized emission distributions along the central axis of each plume for (red) ionic and (orange) neutral species at pulse energies of (a) 1.9 mJ and (b) 3.8 mJ representative of the single and multiple filament regimes, respectively.
