摘要：

The results of measurements of the nonlinear kinetics of QDs when excited by 20 ps laser pulses of various intensities are presented. It was found that the front of the obtained kinetics is modulated by vibrations of the order of the excitation pulse duration. Determined, that the frequency and amplitude of these oscillations depend on the intensity of the laser pulse.
