By examining the interaction of two copropagating ultrafast optical pulses in a semiconductor multiple quantum well, we experimentally determine the temporal dependence of the induced polarization. Based on this technique we observe that the optically induced density goes through a maximum at sufficiently high excitation intensity. Microscopic calculations show that the observed phenomena are a manifestation of Rabi flopping in semiconductors.
