Abstract The quasistatic magnetic field generated by a short laser pulse in a uniform rarefield plasma is found analytically and compared to two-dimensional particle-in-cell simulations. It is shown that in a frame moving with the pulse the magnetic field contains a component which is homogeneous in longitudinal direction and a component which is oscillating at the wave number 2{ital k}{sub {ital p}}, where {ital k}{sub {ital p}} is the wave number of the plasma wake. Particle simulations confirm the analytical results and are also used to treat the case of high intense laser pulses with {ital v}{sub {ital E}}/{ital c}{approx_gt}1. The resultant magnetic field has a focusing effect on relativistic electrons in the plasma wakefield accelerator context. {copyright} {ital 1996 The American Physical Society.}
