Abstract
The nonlinear absorption and refraction of octasubstituted metallophth alocyanines (R(8)PcM: M = 2H, Cu) in solution is measured in the picos econd regime by the Z-scan technique at a wavelength of 1.064 mu m. Th e results at different pulsewidths show that the nonlinear absorption process is dominated by two-photon absorption in the metal-free compou nd, and by excited state absorption in the Cu-substituted molecule.
