Nonlinear absorption spectroscopy of a bis(Porphyrin)-substituted squaraine
The nonlinear absorption mechanisms of a bis(porphyrin)-substituted squaraine have been studied with femtosecond, picosecond, and nanosecond pulsewidths. The two-photon absorption is ~10× larger than those of the constituents and is explained by intra-molecular charge transfer. © 2009 Optical Societ...
