In the laser wakefield accelerator, a short ([tau][sub L][lt]1 ps), high power (P[gt]10[sup 12] W) laser pulse propagates in plasma to generate a large amplitude (E[gt]1 GV/m) wakefield. We present an axisymmetric nonlinear fluid model that allows simulation of laser pulse propagation through a plasma on the plasma time scale. We find that a laser pulse will propagate through a plasma for many vacuum diffraction lengths if either of two conditions are met: (1) an appropriately shaped plasma density channel can be obtained or (2) an ultrahigh power tailored laser pulse can be created.
