Optical parametric processes in isotropic third-order nonlinear media withmagneto-optic properties

Optical parametric interaction in isotropic third-order nonlinear media wit h magneto-optic properties is investigated. It is shown that new phase-matc hing conditions with a magneto-optic contribution are possible. In particul ar, we study four-wave mixing and electric field-induced three-wave paramet ric processes in the presence of a magnetic field applied along the directi on of propagation of the interacting waves. Control of the new phase-matchi ng branches can be achieved by tuning of the magnetic field. (C) 2000 Optic al Society of America.
