FIG. 3.

(a) Pump-push-probe of PFO solution in the channel taken at 5 ps (open circles), 6 ps (solid line), and 7 ps (filled squares) after the pump pulse. Inset: normalized dynamics taken at 460 nm (open circles) and 600 nm (filled squares). (b) Pump-push-probe dynamics (open circles) and pump-probe dynamics (open squares) of PFO solution and (c) PFO solution at 480 nm. Time-scale shifted to place zero at arrival of push.
