Abstract
A two-dimensional axisymmetric model of the propagation of intense femtosec ond laser pulses through dispersion-free transparent media is described. Th e effects of diffraction, nonlinear Kerr effect (instantaneoas and retarded ) and multiphoton ionisation are included. Numerical results concerning air and other gases are discussed. In particular, time self-compression of fem tosecond pulses is predicted. Stable self-guided pulses are simulated, in a greement with recent experimental observations.
