FIG. 1.

Schematic diagram of the experimental set up used for pump-probe studies at 600 nm.

FIG. 2.

Open aperture Z-scans of Po1-Po5 at different wavelengths at 560 nm, 580 nm, and 600 nm indicating 2PA behavior. Some of the plots have been shifted vertically for clarity.

FIG. 3.

(a)-(e) Excited state dynamics data of Po1-Po5 obtained using ps pulses at 800 nm. Noisy lines (Black lines) represent the experimental data, while the smooth solid lines (red lines) are fits to the data.

Image of FIG. 4.
FIG. 4.

(a)-(e) Excited state dynamics of Po1-Po5 using ∼70 fs pulses at 600 nm. The data were obtained using focused pump/probe beams. Noisy lines (Black lines) represent the experimental data, while the smooth solid lines (red lines) are fits to the data.

Image of FIG. 5.
FIG. 5.

Excited state dynamics of Po1, Po2, and Po4 using ∼60 fs pulses at 600 nm using unfocused pump/probe pulses. Noisy lines (Black lines) represent the experimental data, while the smooth solid lines (red lines) are fits to the data.
