Paratellurite single crystals have good acoustooptical properties that are important for various devices, such as deflectors,
modulators, and tunable noncollinear filters. Paratellurite single crystals of up to 80 mm in diameter and 100 mm in height
were grown using the Czochralski method from ultrapure melts. Optical anomalies in the grown crystals—gas bubbles, striations,
impurity inclusions with nearby stresses, and regions with high dislocation densities—were studied with chemical, X-ray, and
optical methods.
