Description
This article investigates the anisotropy of acousto-optic interaction in langasite crystals. The study analyzes the directional dependences of the effective photoelastic coefficient and acousto-optic figure of merit, which are important for selecting optimal crystal cuts and geometries for acousto-optic devices. The paper was originally published in Scientific Reports of Bukhara State University, 2024, issue 12, pp. 69–74.
Abstract (English)
Langasite crystal (La₃Ga₅SiO₁₄) is widely used in various acoustic and acousto-optic devices. Of particular interest is the use of these crystals as an active medium for controlling the intensity of diffracted light. In this article, the elastic and photoelastic constants of these crystals were determined by the Bragg diffraction of acoustic waves. Using the obtained values, the acousto-optic figure of merit (M2) was determined, which depends on the direction of propagation of longitudinal acoustic waves in the crystallographic plane (100). The results of experiments and calculations made it possible to determine the geometric structures of Bragg diffraction of light with the highest acousto-optic efficiency.
