Co-operative gamma ray generation stimulated by X-ray pulse: Co-operative gamma ray generation

Abstract

The second-order coherent function at two-photon cooperative emission is investigated. As was observed the co-operative generation of γ-ray light is possible if the duration of X-ray pulse is longer than the co-operative delay super-radiant time of gamma photons. In this case, the amplitude of the X-ray field is constant in the process of co-operative γ-photon emission and the quasi-energetic levels for the extended nuclei system are dressed. Achievement of viable two-photon sources of correlated photons in optical, X- and gamma-rays diapasons would have major impact applications in biological and medical diagnostics of bio-molecules, viruses etc. © 2012 Springer Science+Business Media B.V.
