Abstract
A nondegenerate pump probe scheme to isolate the electron dynamics is investigated. The pump pulse excites electron from the heavy-hole and the light-hole valence bands while the probe pulse tests the absorption saturation of the interband transition from the split-off (SO) valence band to the conduction band. Because of the large spin-orbit splitting in GaAs no holes are present in the SO band and the differential absorption signal depends on the electron distribution only. Furthermore, this method allows the observation of spectral hole burning as a result of the initially injected electron population without any contribution from the induced-grating coherence effect.
