Abstract We report a novel technique for the detection of hypersound by means of phonon-photon double resonance. This technique seems especially suitable for very-high-frequency phonons. Experiments were performed in the X-band with a modified apparatus for Electron Paramagnetic Resonance (EPR) combined with a hypersound pulse-echo equipment. Phonon pulses of about 1 μs duration could be detected in the paramagnetic systems MgO: Fe3+ and MgO: Fe2+. This kind of incoherent phonon detector is sensitive only in a narrow frequency band, can be tuned, and can easily be applied in several frequency ranges without changing the experimental set-up.
