Tellurium Dioxide Crystals (TeO₂)

G&H Tellurium Dioxide (TeO₂) crystals are premier materials for acousto-optic applications, offering exceptionally high acousto-optic figure of merit and optical transparency in the visible to near-infrared range.

TeO₂ is ideal for use in acousto-optic modulators, deflectors, and frequency shifters, providing low acoustic attenuation and high diffraction efficiency. Its birefringent and non-hygroscopic nature makes it suitable for stable, long-term operation in a variety of photonic systems.

G&H supplies high-quality TeO₂ crystals precisely oriented and fabricated for optimal acousto-optic performance in both free-space and fiber-coupled configurations. Its strong birefringence and slow shear velocity make it a leading choice for high-resolution beam control.

TeO2 (tellurium dioxide), ideal for acousto-optic (AO) devices, including rotators, modulators, resonators, and tuning filters. The resolution of AO devices made of TeO2 crystals increases several levels above others, and the crystal is widely used in astronomy, remote sensing, and many other application areas.

TeO2 is a particularly good example of G&H’s unique vertical integration and unrivalled, all-encompassing control of every stage of the supply chain, from raw material growth to full sub-system completion. We grow the crystals in our Cleveland facility, we process and develop TeO2 AO cells in our Fremont facility, and from these we manufacture our award-winning Fiber-Q ® acousto-optic modulators in Torquay, UK. These are then integrated into sub-systems for sensing applications.
