We present the results of the proof of principle experiment on the observation of the acoustic oscillations induced by the pulsed laser excitation. Time domain spectra agree well with the model of the frequency modulation of Mössbauer radiation passing through a vibrating resonance medium. The ratio of the fourth and second Fourier harmonicsD 4 Ω/ D 2 Ωof the modulated radiation is suggested to measure the modulation index since this ratio is very sensitive to the amplitude of nuclear vibrations. The proposed methodology may be used for the study of opto‐acoustic phenomena.
