Polarization coherent anti‐Stokes Raman scattering (CARS) is shown to provide a means to selectively and independently address optical nonlinearities of materials constituting a multicomponent nanostructure, thus suggesting the way to tailor the nonlinear‐optical response of nanocomposite materials. Polarization properties of CARS in porous glass infiltrated with a toluene solution are experimentally studied. Rotation of the polarization analyzer with respect to the polarization vectors of the linearly polarized pump fields is shown to radically modify CARS line profiles, indicating changes in the ratio of CARS signal components related to toluene molecules and the porous glass host.
