Abstract

An interferometric approach according to a single-pass Mach-Zehnder interferometer was used to investigate the photoelasticity of the Ca3TaGa3Si2O14 (CTGS) crystal. The highest number of sample orientations for piezo-optic studies was used to demonstrate the accuracy of piezo-optic coefficient determination. Basing on the matrices of piezo-optic coefficients and of elastic stiffness coefficients, all the coefficients pik of the elastic-optic matrix are computed. The acousto-optic efficiency is assessed for the highest value of pik coefficient. The data from CTGS are validated with the similar values for La3Ga5SiO14 (langasite) crystals. CTGS M2 = 1.66·10-15 s3/kg has the greatest acoustooptic figure of merit, which is two to three times higher, compared to langasite, and strontium borate, respectively and are frequently employed in the UV spectral range for acousto-optic light modulation.
