Abstract
The onset and recurrence of multiple light filaments during the long-distance propagation of intense femtosecond infrared pulses in air is shown to share features with strong turbulence in other physical systems. Here, however, space-time collapse events drive the turbulence, and plasma defocusing, not dissipation, is the dominant mechanism regularizing the collapse.Keywords
