We study the generation of nonlinear plasma wake fields by intense laser pulses, using an Eulerian code for the numerical solution of the fully relativistic one-dimensional ($1D$) Vlasov-Maxwell equations. The examination of the phase-space of the distribution function allows to study without numerical noise aspects of the particle acceleration by the wake-field generated by intense laser pulses, in the very low density regions of the phase-space. We study the effect of the thermal spread on the existence of accelerated beams, and we compare between results obtained from a circularly polarized wave and a linearly polarized wave.
