X-ray imaging of the surface acoustic wave propagation in La3Ga5SiO14 crystal

Direct imaging of a 10 mu m surface acoustic wave (SAW) propagation in a La3Ga5SiO14 crystal was obtained on the European Synchrotron Radiation Facility (ESRF) synchrotron radiation source in the sagittal diffraction geometry using the Talbot effect. Imaging of the SAW wave field with the period 10 lm was observed at a distance corresponding to the half of the Talbot distance. It is shown that the presence of the growth banding in the crystal does not influence the propagation of acoustic wave-fields in the crystal nor does it cause a distortion of the SAW wave front.
