Compression of the Waveform of a Gamma Photon Into a Train of Short Pulses in an Optically Dense Oscillating Mössbauer Absorber

详细

We study the potential of a method for manipulating the spectral-temporal characteristics of the Mössbauer γ photon on the basis of resonant interaction of the electromagnetic field of a single photon with an oscillating nuclear absorber. It is shown that the absorber enrichment by a resonant nuclide and an increase in its optical density allow one to considerably increase the peak probability of detecting the photon behind the absorber and improve the obtained-pulse shape. The estimates for the γ radiation of the Mössbauer nuclide ⁵⁷Co with a photon energy of 14.4 keV and a lifetime of 141 ns of the excited state, which interacts with the oscillating resonant absorber enriched by the ⁵⁷Fe nuclei, are given and the possibility of compressing the waveform of an incident photon into a train of pulses with durations of 10 ns and peak intensity two times exceeding that in the absence of the absorber is shown.
