Polarization dependent degenerate-four-wave-mixing experiments on semiconductors (ZnSe, CdS) and dielectrics (NaCl, PbF2) reveal the essential mechanisms of the bound-electronic chi((3)). We show, for the first time, that the observed anomalous dispersion of the polarization dependent phase-conjugate reflectivity can be explained using a simple 3-band model, The near vanishing reflectivity in the two-photon coherence geometry is shown to be a consequence of the interference between transitions originating from heavy- and Light-hole valence bands, We also present measurements on the polarization dichroism of the nonlinear refractive index (n(2)), in good agreement with this simple theory.
