Abstract Absorption recovery kinetics data on the picosecond time-scale of a high signalto-noise ratio can be obtained by using continuously operating synchronously modelocked dye lasers. We show that such data make it possible to determine multiple exponential decays with small differences in rate constants. We also show that an absolute prerequisite to accomplish this is that the measurements are performed at a number of different wavelengths, and that the decays are monitored in a time interval corresponding to several lifetimes. These considerations are demonstrated by measurements on two carbocyanine dyes, DQOCI and pinacyanol, respectively.
