Abstract

Two consecutive ultrashort laser pulses separated by 100 fs and polarized in orthogonal directions are shown to form a long femtosecond filament that connects both filaments created independently by each pulse from the interplay between photoionization and self-focusing. Measurements of the electron density generated by photoionization of air show that this connection is obtained for a very specific time delay between the pulses. A strong shortening of one of the pulses is associated to this connection of plasma channels. This phenomenon is modeled via numerical simulations of the propagation and interaction of the pulses.
