Abstract

Light-induced noncentrosymmetry was achieved experimentally in acceptor–donor-substituted azobenzene solutions and observed by phase-matched nondegenerate six-wave mixing. The microscopic origin of the induced noncentrosymmetry was found to be orientational hole burning, which was distinguished directly with net orientation of molecules by experimental observations. The decay time of the induced noncentrosymmetry depended on the rotational orientation time of the sample’s molecule, which varied linearly with the viscosity of the solvent.
