Abstract :
Summary form only given. Two-beam four-wave mixing (FWM) experiments on bulk GaAs at low temperatures using pulses of 15 fs in duration have recently revealed two observations: i) non-Markovian relaxation resulting from exciton-LO-phonon interaction at intermediate carrier densities and ii) an apparent contradiction between the observed decay in the time delay domain and the FWM-linewidth at low densities.
