The influence of carrier-carrier scattering on intraband coherence is studied by analyzing the dephasing of the THz emission from optically excited Bloch oscillations in a GaAs/AlGaAs superlattice. Intercarrier collision-induced dephasing is investigated by varying both the density of coherent scatt
