ResumoWe present here the generation of forward phase conjugate waves (FPCWs) by means of degenerate multiwave mixing with three-dimensional geometry in C60 arachidic acid (C60−AA) complex Langmuir-Blodgett films. The FPCWs are induced by third- and higher-order (5th-order) nonlinear effects of the films. The 3rd-order susceptibility χ(3) was measured to be 1.8 ×10−8 esu for the film at 532 nm wavelength. In the meantime, optical storage effects in C60−AA complex LB films were observed. The origin of the effects is considered mainly due to the light-induced transformation between the aggregate and monomer structure of C60 molecules.
