Formulation of the problem. Acousto-optic modulators (AOMs) are important components in optoelectronic systems used for controlling light beams with sound waves. The efficiency and performance of AOMs largely depend on the properties of the crystalline structures used. This study investigates the main parameters of crystalline structures that influence the characteristics of AOMs.

Target. To identify and analyze the key optical parameters of crystals used in acousto-optic modulators, such as refractive index, acousto-optic quality coefficients, thermal stability, and other important factors.

Results. The most significant characteristics affecting AOM operation have been identified, and the refractive index and optical density of various crystals have been obtained, along with an evaluation of the acoustic interaction coefficient and thermal properties of the crystals.

Practical significance. A foundation has been laid for creating a more realistic mathematical model of the acousto-optic modulator that describes all internal processes and distortions during its operation.

The work was carried out at the expense of state assignment No. FSFZ-2024-0006.
