Abstract :
Summary form only given.We present numerical simulations of nonlinear pulse propagation in air to elucidate the physical mechanism of the phenomenon. Our comprehensive model for propagation ia air includes the effects of self-focusing multiphoton absorption, group-velocity dispersion (GVD), absorption and defocusing due to the generated electron density.
