摘要：
Temporal behavior of hot carriers in CdSe is investigated with subpicosecond accuracy, by using a novel pump-probe technique, in which the self-phase modulation effect in an optical fiber is utilized to extend the spectral width of the probe pulse. Pump-pulse-induced changes in the spectrum of the probe pulse are compared with a calculation that takes into account the formation of a high-density electron-hole plasma, and a succeeding thermal relaxation of the plasma. Excellent agreement between theory and experiment is obtained, when the carrier-LO phonon interaction is included. © 1990.
