Реферат: The method of longitudinal scanning is used for measuring the dispersion of the nonlinear index of refraction and nonlinear absorption coefficient of thin films of pseudoisocyanine J-aggregates. The measured quantities were used for calculations of the imaginary and real parts of the cubic susceptibility. Numerical calculations of the dispersion of the real part of the nonlinear susceptibility are carried out based on the Kramers-Kronig relations and the data obtained for the imaginary part. It is shown that the imaginary part of the cubic susceptibility is determined by the transient bleaching of the exciton absorption peak of J-aggregates. The observed features of the cubic susceptibility dispersion are explained within the framework of the four-level diagram of the exciton transitions in J-aggregates.
