## Abstract We observed excitonic Rabi oscillations (ROs) in quantum dots (QDs) by fourβwave mixing (FWM) and pumpβprobe techniques. When a large number of QDs are excited by a spatially nonuniform laser, the inhomogeneous distribution of the transition dipole moments of the QD excitons and the spa
