Özet

Single-beam z-scan and transient absorption experiments were carried out between 400 and 1000 nm in Gd-2 at C-80 thin films and solutions. The third-order nonlinearity was large, negative, and strongly dependent on pulse duration and wavelength. Transient absorption results suggest that the fast nonlinear response is enhanced by two-photon-induced ground-state absorption and excited-state bleaching effects.
