“…Accordingly, for accurate determination of these POCs we applied a conoscopic interferometry following the methodology described recently by Mytsyk et al [ 22 , 36 ]. Earlier, Wang et al [23] have demonstrated an application of similar technique for probing of electrooptic coefficients in strontium calcium barium niobate crystals. Fig.…”

“…Here we have taken into account that the fourth rank tensor of the elastic compliance is symmetric with respect to the pairs of indices ( S km = S mk ), thereby S 31 = S 13 and S 32 = S 23 . Tetragonal symmetry 4 mm , in addition, reduces a number of independent tensor components, particularly, S 13 = S 23 . Similar expressions may be easily derived for all the other principal POCs, im ( k , i , m = 1, 2, 3), related, particularly, with the piezooptic measurements performed on the principalcut-sample [ Fig.…”

“…For this reason the polarization-optical technique [21] and conoscopic interferometry [22] have recently proposed to determine relevant constants more accurately. Earlier the conoscopic interferometry has been applied also to study the linear electrooptic effect in photorefractive crystal materials [23] .…”

Mach-Zehnder and conoscopic interferometry are used to explore photoelastic properties of anisotropic crystal materials. In a number of cases an application of both techniques significantly improves an accuracy of piezoop-tic and photoelastic measurements. The performance of such combined approach is demonstrated on tetragonal lithium tetraborate (LTB) single crystals, as an example. Special attention is paid to methodological and metrological aspects, such as measurement accuracy and the quantitative error analysis of the resulting measurements. Performing the interferometric measurements for different geometries of piezooptic coupling the full sets of piezooptic and photoelastic tensor constants of LTB crystals have been determined. The acoustooptic efficiency, on the other hand, has been evaluated using the magnitudes of photoelastic constants derived from the piezooptical measurements. For the geometries with strong photoelastic coupling LTB demonstrates quite large acous-tooptic performance with figure of merit value, М 2 , achieving 2.12 × 10 -15 s 3 /kg. It is several times larger than that of strontium borate crystals, nowadays the best acoustooptic material in deepultraviolet spectral region.
