Transverse structure and energy deposition by a subTW femtosecond laser in air: from single filament to superfilament

Transverse structure and energy deposition by a subTW femtosecond laser in air: from single filament to superfilament

We traced experimentally transition from a single air filament to the superfilament under action of powerful loosely focused (NA ∼ 0.0021) femtosecond beam. Two regimes were exploited with multifilament formation by artificial amplitude or intrinsic amplitude/phase front modulation of the beam havin...
