Abstract: | The spontaneous emission from an atomic ensemble localized in a microcavity with the participation of microcavity photons
and an external broadband quantized electromagnetic field at the Raman resonance of photons with an optically forbidden (two-photon)
atomic transition has been studied. The average spontaneous decay intensity has been calculated for simple cases. It is shown
that the dynamics of spontaneous emission from this atomic ensemble differs generally from the conventional superradiance
(spontaneous emission of an atomic ensemble at a one-photon optically allowed transition from excited to the ground state.
When the atomic ensemble is strongly excited, the delay times and the emission pulse shape differ significantly. The parameter
ranges where the spontaneous emission from the atomic ensemble under consideration at a two-photon Raman transition can be
described as conventional superradiance with renormalized parameters are found. In the case of single excitation the photon
emission probability depends on the number of photons and atoms in the microcavity. |
