Abstract

The topic of this chapter is a description of the superintense laser beam temporal dynamics in media with relativistic and charge displacement nonlinearity in the framework of the nonlinear Schroedinger equation model and self-channeling simulations on the basis of the more advanced wave equation model. The former approach makes it possible to establish a picture of laser pulse dynamic self-modulation in a plasma and the giant broadening of its spectra entailed by this effect, as well as to examine the dynamics of the two-dimensional intense laser pulse solitons. The advantage of the latter one is the complete description of the wave properties of propagation. In particular, simulations performed with the help of the wave equation with relativistic and charge-displacement nonlinearity illustrate the process of the prepulse formation. The numerical technique for treating the wave equation studied is presented in [161], and the numerical results are discussed below following [115]. The simulations are carried out in the axially symmetrical case.
