Paper Abstract

The nonlinear optical process which permits the optical preparation of centrosymmetric materials for frequency doubling is described in terms of an orientational hole-burning effect induced through non-zero E3 resonant six-wave mixing. The transient all-optical poling of solutions of organic molecules is demonstrated in a configuration of phase-conjugation pumped at half frequency. A permanent all-optical poling is achieved by seeding preparation under backward and forward geometries in an azoaromatic acrylic copolymer. Figures of merit of the optical nonlinearities relevant to the frequency-doubling process are established. This offers a new molecular engineering route to the control and optimization of phase- matched oriented microstructures for frequency conversion.
