Theoretical study on near-resonant third-order nonlinear optical properties (gamma) of dendritic molecular aggregates: Intermolecular-interaction and relaxation effects on gamma
Second hyperplarizability (gamma) of dendritic molecular aggregate (D25) is calculated using a coupled-dipole model in the Markoff approximation. At the near resonant region, intermolecular-interaction and relaxation effects on gamma are found to remarkably change the gamma value.
