Abstract
The coherent and incoherent components of the resonant secondary emission f rom GaAs quantum well structures after ultrashort excitation have been stud ied as a function of the excitation density and inhomogeneous broadening. W e find that the coherent emission saturates with the excitation power in go od agreement with a simple model taking into account the exciton inhomogene ous broadening and the excitation induced dephasing.
