Four-wave Stokes k-spectra for light scattering on polaritons in lithium niobate crystals with an Mg impurity are studied experimentally. The
mechanisms for direct, cascade, coherent, and incoherent four-wave mixing of light are discussed in the course of interpreting
the angular dependences of the scattered light intensity. It is shown that the dispersion of the real part of the polariton
wave vector and the refractive index of the crystals at the polariton frequencies can be measured with an order of magnitude
greater accuracy than by spontaneous three-wave polariton light scattering. A significant discrepancy is found between determinations
of the polariton absorption coefficient from the angular spectra of three-wave scattering and four-wave scattering in terms
of the model employed here.
