Abstract
The effect of ultrasound artificial anisotropy of crystals in X-ray frequency range was observed and an effort to theoretically interpret this effect in Bragg-Laue diffraction case was made. It was established that an isotropic crystal optically turns into an artificially anisotropic one with optical axis along the direction of applied external influence as a symmetry axis, giving rise to the double refraction. Investigations of this kind are important because the results can be applied such as the artificial anisotropy effects in optics (in analogy Kerr effect in optics).
