Transformation of Mossbauer gamma-ray photon waveform into short pulses in dual-tone vibrating resonant absorber

The transformation of exponentially decaying waveform (the time dependence of detection probability) of a Mossbauer gamma-ray photon into a regular sequence of short nearly bandwidth-limited pulses in a vibrating recoilless resonant absorber is studied. The case of dual-tone vibration at the fundamental frequency and its second harmonic under experimentally feasible conditions is considered. We show that this technique allows one to shorten pulses and increase the ratio of pulse separation to pulse length as well as to enlarge pulse amplitude compared to the pulses produced in harmonically vibrating absorber. The obtained results pave the way to the development of the time-resolved Mossbauer gamma-ray spectroscopy and manipulation of quantum information in hard x-ray/gamma-ray range.
