We have observed stimulated scattering in a II-VI microcavity at 80 K under nonresonant excitation conditions. This stimulated scattering manifests itself through probe amplification in a pump-probe reflectivity experiment and through a highly nonlinear emission at an energy corresponding to a k? ? 0 state on the lower polariton branch. We were able to follow the onset and decline of stimulated scattering by measuring the temporal evolution of the probe amplification.
