Abstract
We present theoretical analysis of noncollinear two-wave spectroscopic schemes taking into account polarization incoherence of arbitrary polarized pumping. Our very general treatment is based on a coordinate-free method of wave operators. The analytical expressions for the signal dependencies on beam-crossing angle (noncollinearity angle) and polarization parameters have been obtained for the cases of saturation spectroscopy, nonlinear polarization spectroscopy and optically heterodyned polarization interferometry (OHPI). The comprehensive studies of the OHPI scheme with noncollinear partially polarized light are given. Three different methods of nonlinear susceptibility measurements are suggested.
