Search for the effect of weak photon localization in second-harmonic waves generated in a disordered anisotropic nonlinear medium

Abstract

The possibility of observing the effect of weak photon localization in the second-harmonic waves generated in KH(2)PO(4) (KDP) powder is investigated and discussed. The two primary factors for the negative observation are that the second-harmonic waves are generated by different primary wave vectors because of multiple scattering of the primary wave in the disordered medium and that the scattering amplitude for the two counterpropagating second-harmonic waves are different because of the anisotropy of the KDP microcrystals.
