NONLINEAR MAGNETO-LIGHT-INDUCED PHENOMENA IN A RESONANT MEDIUM

A general theory of magneto-light-induced rotation of the plane of pol arization of the probe signal in resonant medium is developed. The pro pagation of an intensive elliptically polarized electromagnetic wave t hrough a resonant medium with arbitrary angular moments of the levels is investigated in the adiabatic following approximation. Then the pro pagation of counterpropagating polarized waves: an intensive pump wave and a probe light signal, through the resonant medium in the presence of the longitudinal magnetic field is studied. It is shown that the i nduced anisotropy of the medium is determined both by magneto-optical and polarization light effects and by their interference. This allowed us to determine the local value of the external spatially-inhomogeneo us magnetic field.
