This is a review of some recent development in femtosecond filamentation science with emphasis on our collective work. Previously reviewed work in the field will not be discussed. We thus start with a very brief description of the fundamental physics of single filamentation of powerful femtosecond laser pulses in air. Intensity clamping is emphasized. One consequence is that the peak intensity inside one or more filaments would not increase significantly even if one focuses the pulse at very… Expand
Femtosecond laser filamentation with a microlens array in air

Beam wandering of femtosecond laser filament in air.
TLDR
With this result, one may be able to estimate quantitatively the displacement of a filament over long distance propagation and interpret the practical performance of the experiments assisted by femtosecond laser filamentation, such as remote air lasing, pulse compression, high order harmonic generation (HHG), etc. Expand
Transition from linear- to nonlinear-focusing regime in filamentation
TLDR
An analytical method is proposed to determine the transition between a collimated and a strongly focused filament, and it is shown that it corresponds to an actual shift in the balance of physical mechanisms governing filamentation. Expand
