FIG. 1.

Femtosecond transient absorption spectrum of BrdU in water, pumped at and probed at . The solid line is the best fit to the experimental data (solid squares). The inset is the peak absorption at as a function of pump power.

FIG. 2.

Femtosecond transient absorption spectra of in water, pumped at and probed at : (a) original data, where the sharp peak at time zero is the coherence “spike” observed when ! and ! are close to each other; (b) spectra obtained after the subtraction of the spectrum for the pure water. The solid lines in (b) are the best fit to the experimental data, giving a rising time and two decay times and .

FIG. 3.

Femtosecond transient absorption spectra of BrdU in water, pumped at with various pulse energies and probed at , after the subtraction of the spectrum for the pure water. The inset is the square root (SQR) of the absorbance peak intensity at vs pump pulse energy.
