Elasto-optic Effect and Its Spatial Anisotropy in Ca3TaGa3Si2O14 Crystals

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
