Abstract: This article studies the evolution of spot size of an intense extraordinary laser beam in cold, transversely magnetized plasma. Due to the relativistic nonlinearity, the plasma dynamic is modified in the presence of transversely magnetic filed. In order to specify the evolution of the spot size of extraordinary laser beam, nonlinear current density is set up and the source dependent expansion method is used. It is shown that enhancing the external magnetic field decreases the spot-size of laser beam significantly, and thus the self-focusing effect becomes more important due to the extraordinary property of laser beam.
