Abstract

We have suggested a highly precise method for determining piezooptic coefficients, which relies on a knowledge of 2D spatial distribution of mechanical stresses in a crystalline disk compressed along its diameter. Relevant theoretical relations that describe piezooptic effect in the crystals belonging to the point symmetry group 3m have been derived. The method has been successfully verified in the experiment dealing with LiNbO3 crystals. [ABSTRACT FROM AUTHOR]

Abstract

In the present work we describe a high-accuracy torsion method for measuring piezooptic coefficients π14 and π25 in trigonal crystals. Spatial distributions of the optical indicatrix orientation and the optical birefringence induced by torsion stresses are quantitatively evaluated and analysed. It is shown that a crystal subjected to torsion stresses works as an optical lens, with the characteristics operated by a torque moment. [ABSTRACT FROM AUTHOR]
