    "abstract": "The filamentational instability of spatially broadband femtosecond optical\npulses in air is investigated by means of a kinetic wave equation for spatially\nincoherent photons. An explicit expression for the spatial amplification rate\nis derived and analyzed. It is found that the spatial spectral broadening of\nthe pulse can lead to stabilization of the filamentation instability. Thus,\noptical smoothing techniques could optimize current applications of ultra-short\nlaser pulses, such as atmospheric remote sensing.",
