We observe polarization-resolved coherent beam combination through nondegenerate two-wave mixing in water-glycerol suspensions of shaped polytetrafluoroethylene microparticles. Coherent energy transfer that arises from translational and orientational moving index gratings was observed. A theory for beam combination through nondegenerate two-wave mixing is presented and found to be in excellent agreement with these measurements.

In these experiments the microparticles were oriented by a high-frequency electric field, and saturation effects were clearly observed in both the Kerr effect and light scattering. The transient dynamics of the Kerr effect was studied and a field-dependent medium response time measured.

The important role of beam polarization is observed, and its part in energy transfer is discussed. A theory that treats polarization effects in transient two-wave mixing is presented, applied to the carbon disulfide experiments, and found to be in excellent agreement with the data.
