ABSTRACT:
A nonlinear optical device having an optical medium and an optical element including a polarizer, an optical resonator and a reflector is provided. The optical medium includes an organic nonlinear optical material represented by a formula: ##STR1## wherein each of R.sub.1 and R.sub.2 is an alkyl group having 2 to 6 carbon atoms or a hydroxyalkyl group having 2 to 6 carbon atoms, R.sub.1 and R.sub.2 being same or different groups; or R.sub.1 is an ethyl group and R.sub.2 is an acryloyloxyethyl group (CH.sub.2 .dbd.CH--COO--CH.sub.2 CH.sub.2 --) or a methacryloyloxyethyl group (CH.sub.2 .dbd.C(CH.sub.3)--COO--CH.sub.2 CH.sub.2 --); and each of X.sub.1, X.sub.2, X.sub.3, and X.sub.4 is individually a hydrogen atom, a hydroxyl group, a halogen atom, an alkyl group, an alkoxy group, an alkyl ester group, or an alkylamide group, where X.sub.1, X.sub.2, X.sub.3 and X.sub.4 may be the same or different groups.
