Photoelastic properties of NaBi(MoO4)2 crystals.

In this work we present the results of comprehensive studies of the piezo-optic and elasto-optic effects in NaBi(MoO) crystals. The full matrices of the piezo-optic and elasto-optic coefficients for the NaBi(MoO) crystals are obtained for the first time, to the best of our knowledge. The acousto-optic effect in the NaBi(MoO) is analyzed for the case of interactions of optical waves with the slowest acoustic waves. It is shown that the crystals under analysis can be efficiently used as working elements for the collinear acousto-optic tunable filters.
