Spectral-hole-burning experiments are performed in the gain region of an inverted semiconductor multiple quantum well. We find not only a spectral hole at the pump-pulse frequency but also replicas at higher frequencies. These replicas are qualitatively explained in terms of carrier-phonon interactions in which high-energy carriers relax into the optically induced spectral hole by LO-phonon emission.
