摘要： The present disclosure relates to tellurite crystals, growing methods of the same, and applications thereof; the crystals a chemical formula of MTe3O8, wherein M=Ti, Zr, Hf, which belongs to an Ia-3 space group of a cubic crystal system, wherein a transmittance waveband ranges from visible light to infrared light, with a transparency ≥70%. According to the present disclosure, a growing method of a tellurite crystal is provided, wherein the crystal may be grown using a flux method, a Czochralski method, or a Bridgman-Stockbarger method. The tellurite crystals may be used as an acousto-optic crystal for fabricating an optical modulation device. The present disclosure takes the lead internationally in growing the tellurite single crystals, the size and quality of which sufficiently meet the demands of practical applications of the tellurite single crystals.
