The ultrafast dynamics of nonequilibrium carriers of LT GaAs was studied using femtosecond spectroscopy. The effects of carrier initial scattering, carrier phonon interaction and carrier trapping on carrier relaxation properties were analyzed. A carrier trapping time of 500fs was measured, which was found to increase with decreasing carrier excess energy.
