Title: Femtosecond Dynamics Of The Optical Stark Effect In Semiconductor-doped Glass
Author: Tsuda S.
Brito Cruz C.H.
Abstract: We report the observation of the optical Stark shift in CdS xSe1-x semiconductor-doped glass excited under nonresonant below gap condition and probed with femtosecond optical pulses. An ultrafast and pure light-induced shift of the band edge is observed. The measured dependence of the band edge shift with the pump pulse peak intensity is linear for pump intensities up to 0.3 GW/cm2. Above this value, departure from linearity is observed. For a pump intensity of 3 GW/cm2, the band shifts by 11 meV. The response of the shift tracks the profile of the pumping pulse. © 1996 American Institute of Physics.
