摘要：

We have investigated optical dephasing in CdSSe mixed crystals by means of time resolved four-wave mixing. Dephasing times of the order of 200 ps are observed for photon energies corresponding to localized exciton transitions. The inhomogeneous nature of these transitions is clearly resolved by the time asymmetry of the four-wave mixing signal. © 1989.
