Within the phenomenological approach with the use of multifocus model of filamentation, the equation for the Wigner function is derived to describe the propagation of high-power femtosecond laser pulse. In the approximation of the Gaussian profile of the mean intensity of laser radiation, the behavior of the laser beam effective radius is investigated.
