要旨:
This work is dedicated to the investigation of the temporal dynamics of stimulated
emission. In contrast to the usual textbook description we investigate
this quantum mechanical amplification process in a time-resolved model where
an initially excited atom interacts with a single-photon wave packet. Based on
the formalism for the quantised description of the atom-field-interaction inside
a cavity we use the comparison of the intensities from three different models
to study the temporal dynamics. We find the result that based on stimulated
emission a photon will be emitted directly during the interaction with an exciting
pulse. Furthermore, we identify signatures for this process in the intensity
profile which will be of central importance for the experimental observation in
the nuclear regime. In order to estimate the rate of stimulated emission for
nuclear transitions we use a model based on the excitation of nuclear collective
states, where the stimulation is achieved by a sequence of two pulses. We
present the results for the number of emitted photons due to stimulated emission
in dependence of the relevant laser parameters.
