Abstract
We present time-resolved pump–probe experiments on a semiconductor in which the signal shape, dominated by perturbed free polarization decay, is strongly dependent on the probe pulse’s spectral shape. This effect can be used efficiently to reduce large spectral oscillations that prevent the observation of weak signals near a narrow spectral structure.
