Paper Abstract

The magnitude and the dispersion of the cubic susceptibility of pseudoisocyanine J-aggregates entrapped in polyvinylpyrrolidone thin films have been determined. (chi) (3)((lambda) ) and (chi) (3)((Delta) (lambda) ) have been measured by four-wave mixing in both degenerate and non-degenerate cases. Z-scan technique was used to separate the Re(chi) (3)((lambda) ) and Im(chi) (3)((lambda) ) contributions to the absolute value of (chi) (3) (DOT) (chi) (3) was found to be approximately (2 divided by 6) 10-6 esu and the relaxation time was 10-13 - 10-12 s.
