Abstract
Single-beam z-scan and transient absorption experiments were carried out be tween 400 and 1000 nm in Gd-2 at C-80 thin films and solutions. The third-o rder nonlinearity was large, negative, and strongly dependent on pulse dura tion and wavelength. Transient absorption results suggest that the fast non linear response is enhanced by two-photon-induced ground-state absorption a nd excited-state bleaching effects.
