Abstract
We have performed ultrafast three-pulse experiments in order to investigate the relaxation of charge carriers from a non-equilibrium distribution in inverted GaAs multiple quantum wells. The first pulse, used to create optical gain, was followed by a conventional pump-probe study. The pump-induced spectral hole inside the optical gain was accompanied by sidebands which occurred about 39 meV above the original spectral hole. These sidebands can be explained in terms of LO-phonon scattering of the charge carriers into the vacancies of the spectral hole.
