Abstract

The phenomenon of stimulated photon echo [1] has already been investigated in a variety of molecular systems but in all cases the magnitude of echo signals has been limited to a small fraction of the pumping pulses intensity. The main reason for that lies in a rapid relaxation of nonequilibrium population of molecular states, which hinder the formation of spectral population gratings responsible for the stimulation of retarded optical pulses.
