The energy relaxation of hot electrons in a strongly coupled, n-type GaAs/AlGaAs superlattice is measured by analysing the temperature and electric-field dependence of the interminiband absorption. Electrons are heated up by an electric-field pulse and the resulting change of the electron temperatur
