摘要：
A detailed theoretical study of the time-integrated signal of spontaneous quasi-elastic secondary emission excited by a pair of phase-locked pulses has shown that coherent control is a promising method for measuring the total dephasing rate of a resonant optical transition. This method may be used to study both the homogeneously and inhomogeneously broadened systems, which is highly important in studies of semiconductor quantum dots. Analysis of components of the secondary emission in the framework of the developed theory has allowed us to find a physically justified criterion for separating the scattering and luminescence signals. The role of spectral filtering of the measured signal in determination of the phase and energy relaxation parameters is elucidated. (C) 2002 MAIK "Nauka/Interperiodica".
