The photoelasticity of the Ca3TaGa3Si2O14 (CTGS) crystal was investigated using an interferometric technique based on a single-pass Mach-Zehnder interferometer. To illustrate the accuracy of piezo-optic coefficient determination, the most sample orientations for piezo-optic investigations were used. All the coefficients pik of the elastic-optic matrix are computed using the matrices of piezo-optic coefficients and elastic stiffness coefficients. The acousto-optic efficiency is measured for the pik coefficient with the highest value. CTGS data is corroborated by similar values in La3Ga5SiO14 (langasite) crystals. When compared to langasite and strontium borate, CTGS M2 = 1.6610-15 s3/kg has the highest acoustooptic figure of merit, which is two to three times higher, and is often used in the UV spectral range for acousto-optic light modulation.
