Diffraction, scattering or absorption experiments on materials using synchrotron X-radiation can provide new and more detailed structural information than using conventional X-ray sources.
The absorption spectra, exponential gain coefficient, diffraction efficiency and effect carrier concentration of the crystal were measured.

The results reveal that besides the nonlinearity and absorption, the diffraction is another important factor that affects the shock formation of an ultrasound beam.
