Energy relaxation by optical phonon emission of photoexcited carriers in bulk GaAs has been studied previously by cw and timeresolved picosecond spectroscopy [1]. In the picosecond experiments substantial deviations were observed between calculated and experimentally determined energy relaxation rates, which were ascribed to screening of the carrier-phonon interaction by the high carrier density [2,3] and generation of a nonequilibrium optical phonon distribution [4].
