Ground state recovery time of organic dye BDN in the solvents dichlorethane and lodoethane was measured by means of the pump-probe technique. In this experiment, the integrated transmisson of a whole pulse train was measured as a function of time delay between pumping and probing pulses. The pulse train used in the experiment is generated by a passively mode-locked Nd : YAG laser. The results obtained agree with solutions of the rate equations for the three level model of bleachable dye.
