TGG.Terbium Gallium Garnet
TGG, or Terbium Gallium Garnet (Tb3Ga5O12), is a synthetic magneto‑optical crystal supplied by Photonchina Co., Ltd. It operates across the 400‑1100 nm wavelength band, with a gap between 470 nm and 500 nm, making it suitable for a range of laser wavelengths. Photonchina offers the material in rod and wafer forms, suitable for integration into Faraday rotators and optical isolators. The crystal’s large Verdet constant and low optical loss are highlighted in the supplier’s data.
The crystal exhibits a typical Verdet constant of about 38 rad·T⁻¹·m⁻¹ at 632.8 nm and a thermal conductivity near 5 W·m⁻¹·K⁻¹, both important for high‑power laser applications. Its laser‑damage threshold is typically around 10⁸ W·cm⁻², allowing use in YAG, Ti:sapphire and ring laser systems. Standard rod diameters are 10 mm and wafer thicknesses 1 mm, often supplied with broadband antireflection coatings. These characteristics ensure stable polarisation rotation with minimal thermal drift.
Customers such as laser manufacturers, telecom equipment makers and scientific instrument producers import TGG for Faraday devices that protect against back‑reflections. Photonchina ships from its Fuzhou facility in Fujian province; buyers should confirm incoterms, packaging specifications and any required certifications directly with the supplier. Because the listing does not disclose MOQ, lead time or payment terms, importers need to request those details before placing an order.

Photonchina Co., Ltd. is located at 15 Binzhou Road, Jinshan Industrial Park, Fuzhou, Fujian 350008, China. The supplier holds a harbour‑level trust tier on the platform and currently shows a response rate of 0 %, with no recorded average response time. Its registration indicates a focus on precision‑optics components for international trade.
The company lists synthetic Terbium Gallium Garnet crystals for export, emphasizing custom specifications such as wavelength range and form factor. No additional certifications, production capacity or client references are provided in the listing, so buyers should request test reports and quality documents as part of due diligence.
Terbium Gallium Garnet (TGG) is a premium synthetic magneto-optical crystal widely used in Faraday rotators and optical isolators across the 400-1100nm wavelength range, excluding the 470-500nm band. This rare earth garnet crystal offers excellent thermal conductivity and high magneto-optic quality, making it essential for laser systems, optical telecommunications, and scientific instrumentation. As a specialized industrial optical component, TGG is traded in rod and wafer forms for import/export in the precision optics and photonics supply chain.

Sourcing TGG.Terbium Gallium Garnet from Photonchina Co., Ltd. - China Import Guide
Before ordering TGG, importers should request a material data sheet confirming the Tb3Ga5O12 composition, Verdet constant value at the intended wavelength, and any provided laser‑damage test results. Verify that the supplied antireflection coating matches the target spectral range and ask for a sample for optical performance testing. Confirm the supplier’s harbour trust tier and seek recent transaction references if possible.
Photonchina ships from the port of Fuzhou; buyers need to agree on Incoterms such as FOB or CIF and confirm container loading requirements for rod or wafer packaging. Lead times are not listed, so a detailed production schedule should be obtained, including any post‑processing steps like coating or annealing. Payment terms are typically negotiated per order; request a pro‑forma invoice outlining the agreed terms before transfer.
Conduct an incoming inspection that includes visual inspection for surface defects, measurement of dimensions, and verification of the Verdet constant using a calibrated polarimeter. Request a certificate of conformity and any relevant test reports, such as laser‑damage threshold and thermal conductivity data. Arrange for functional testing within the intended optical system to ensure the crystal meets performance expectations.
