In this paper we report on optical pump-probe measurements on BDN-doped polycarbonate irradiated with laser pulses ranging from 25fs to 1.2ps in duration and up to fluences of 0.1 J/cm(2) at 800nm wavelength. Transient change of the transmission has been measured as a function of pump-probe delay and pump fluence. Pulse duration dependent channels of saturation have been identified and the ground state repopulation (GSR) time has been determined.
