Anisotropy of piezo- and elastooptical effect in β-BaB2O4 crystals

At first using the elaborated software the indicative surfaces of the piezooptical tensor and their stereographic projections were constructed for the β-BaB 2 O 4 crystals. On this basis the spatial distribution of the longitudinal and transverse piezooptical effect was analysed and the extremal values and anisotropy power for each indicative surfaces were determined. The magnitudes and signs of all elastooptical coefficients were calculated and the conclusion about the possibility for use of the β-BaB 2 O 4 crystals as efficient acoustooptical material was done.
