Abstract ： The quasistatic magnetic field created in the interaction of intense ultrashort laser pulses with underdense plasmas has been investigated by two-dimensional particle simulation. The relativistic ponderomotive force and plasma wave excited in self-modulation processes can drive intense electron current mainly in the propagation direction. As a result, an azimuthal, multi-mega Gauss order quasi-static magnetic field can be generated around the laser beam.
