Journal ArticlePlasma, Accelerator, and Nuclear PhysicsTwo-pulse excitation of a molecular quantum wake in air during filamentary propagation is shown to controllably shape an intense femtosecond probe pulse and to significantly extend the filament compared to single-pulse excitation. The effect is sensitive to pump-probe delay on a ∼10-fs time scale.
