Computer simulation of cylindrical laser beam self-focusing in a plasma

A comparison of the beam propagation method (BPM) in two transverse dimensions and for a cylindrically symmetric laser beam with a direct FFT based method is presented for self-focusing of laser beam in a plasma with saturating type (ponderomotive) nonlinearity and cubic nonlinearity.
