(REVIEW)<\/strong><\/h2>\n\n\n\n<p><strong>Abstract. <\/strong>TeO\u2082 crystals, widely recognized for their exceptional acousto-optic and optical properties, are essential materials in modern spectroscopic, telecommunications, and defense technologies. This review highlights the key aspects of TeO\u2082 crystal research, including raw material preparation, growth methods, and characterization of their properties. Currently, researchers are focused on two major directions: enhancing the efficiency of existing growth techniques and addressing the challenges posed by scaling up the size of high-quality crystals. TeO\u2082 crystal growth methods, such as the Czochralski, Bridgman, and hydrothermal processes, face significant challenges, including sensitivity to thermal gradients and the need for high-purity raw materials. The presence of impurities, such as Fe and Pt, strongly influences the optical and structural quality of the crystals. Additionally, the formation of defects, such as bubbles and inclusions, remains a critical issue. This review emphasizes the importance of developing new furnace designs, optimizing thermal conditions, and implementing innovative growth strategies to achieve high-quality crystals suitable for industrial applications. The scalability of TeO\u2082 crystals remains a key challenge that demands further exploration, particularly for their use in large-scale acousto-optic devices.<strong><\/strong><\/p>\n\n\n\n<p><strong>Key words:<\/strong><strong> <\/strong>acousto-optics, single crystals, tellurium dioxide, crystal growth, Czochralski Method.<\/p>\n\n\n\n<p><strong>DOI: <\/strong><a href=\"https:\/\/doi.org\/10.52150\/2522-9117-2024-38-542-565\">https:\/\/doi.org\/10.52150\/2522-9117-2024-38-542-565<\/a><\/p>\n\n\n\n<p><strong>For citation:<\/strong> Babachenko, O.\u00a0I., Liubeka, I.\u00a0M., Kononenko, G.\u00a0A., Podolskyi, R.\u00a0V., Safronova, O.\u00a0A. &amp; AgarkovK.\u00a0V.
