Abstract
We report on specific experiments of optical phase conjugation by non-degenerate six-wave mixing processes involving fifth-order nonlinear susceptibilities. Both processes are enhanced by simultaneous one- and two-photon resonances with the second-harmonic of Nd:YAG laser. We show that light induced second-order susceptibility is much more efficient in noncentrosymmetric (Diethylaminonitrostolbene) than in centrosymmetric (Polydiacetylene) molecules in solutions. We obtain a 2.5 fm/v 210 picosecond-lived phase-matched frequency-doubling susceptibi1ity. The effect is an orientational hole burning in the isotropic distribution of non-centrosymmetric molecules.
