   Consider the case of interaction of two perpendicularly polarized waves in nonlinear media with cubic nonlinearity. [1] The equations describing the self phase modulation of the fundamental wave A and the generation of new wave perpendicularly polarized wave B in condition that |B| << |A| (i.e. when the depletion of the fundamental wave is neglected, self and cross phase modulation of wave B ...

5. Magneto-optic Kerr effect - Wikipedia

   en.wikipedia.org/wiki/Magneto-optic_Kerr_effect

   When the magnetization vector is perpendicular to the reflection surface and parallel to the plane of incidence, the effect is called the polar Kerr effect.To simplify the analysis, and because the other two configurations have vanishing Kerr rotation at normal incidence, near normal incidence is usually employed when doing experiments in the polar geometry.
