Abstract
By an electroabsorption spectroscopy technique, we determined the third-ord er nonlinear optical susceptibilities dispersion in 1-methyl-1'-octadecyl-2 ,2'-cyanine perchlorate Langmuir-Blodgett (J-aggregate) films in the range of 1.8 to 2.7 eV. In addition, from the values of the polarizability change in the monomer and aggregate films, the number of molecules in an aggregat e was evaluated to be 3-4.
