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.
