Abstract
The intrinsic dephasing time of an exciton polariton is investigated in the time domain by use of a time-resolved coherent two-photon exciation and probe technique. This method allows discrimination of the elementary interaction processes of the exciton polariton in semiconductors. The results obtained in CuCl show the role of the different phonons in the exciton-polariton dephasing.Keywords
