摘要：
The interaction of an optically induced nonstationary electron-hole plasma with coherently excited optical phonons in GaP has been investigated through time-resolved coherent anti-Stokes Raman spectroscopy. Nonexponential optical-phonon dephasing is observed in the presence of the electron-hole plasma. A model describing the interaction between the optical phonons and the electron-hole plasma is presented. A comparison of results from the theoretical model and from the experimental data indicates good agreement.
