Toward flexible intensity control of resonantly scattered γ-rays using multi-frequency vibrating resonant absorber
Original language description
We report a method for coherent control of γ -photons, enabling the shaping of γ -ray intensity in nearly arbitrary waveforms. Different intensity waveforms are created by adjusting the motion profile of a resonant absorber (an ensemble of Mössbauer nuclei) and tuning the energy of the incident radiation. A crucial aspect of this method is the use of a low fundamental frequency of vibrations, which broadens the possibilities for γ -ray control. The results of numerical simulations are experimentally validated by generating single and double γ -pulses and inducing short-term absorption. For this, a resonant absorber containing 57Fe nuclei was vibrated with different motion profiles composed of 12 harmonics with a fundamental frequency of 1 MHz. The proposed technique represents an advancement in the manipulation of γ -rays, and potentially x rays, paving the way for the performance of unique types of γ -ray or x-ray quantum experiments and the development of tools such as adjustable table-top γ -pulse sources or γ -ray or x-ray delays and gates. Moreover, inverse application of the method enables investigation of motion at the picometer scale.
