We investigate quasi-stationary magnetic field generation by a high frequency electromagnetic wave in an inhomogeneous plasma using kinetic theory. A general expression for the nonlinear current is calculated which contains previous results in the collisional, cold and warm plasma regimes as special cases. In addition, the contribution of nonlinear Landau damping is studied, which appears to be significant for Langmuir turbulence. The space-time evolution of the quasi-stationary magnetic field is calculated analytically in different regimes of laser-plasma interaction. © 1984.
