Abstract : Nonlinear optical processes in #-electron organic and polymer systems have attracted considerable interest because their understanding had led not only to compelling technological promise but also to new phenomena, new theoretical insights, and new materials and devices. The #-electron excitations occurring on the individual molecular, or polymer chain, units are the basic origin of the observed nonresonant nonlinear optical coefficients which are oftentimes unusually large. The coefficients are broad band and ultrafast, and, as shown by theory and experiment, their sign, magnitude and frequency dependence are determined by many body electron correlation effects. This level of understand, in turn, now makes viable computer aided molecular design of new nonlinear optical chromophores.
