Product Description
Gadolinium Gallium Garnet (GGG) Magneto-Optical Crystal
Gadolinium Gallium Garnet (GGG, Gd3Ga5O12) is a high-performance synthetic crystalline material from the garnet family, offering exceptional mechanical, thermal, and optical characteristics. This colorless crystal features a cubic lattice structure and is manufactured using the Czochralski method, with optional dopants available for color modification. GGG serves as an ideal substrate for magneto-optical films and finds applications in advanced optical components and as a premium diamond simulant in jewelry.
Key Performance Advantages
- Large crystal dimensions up to 4 inches diameter
- High thermal conductivity of 7.4W/m·K
- Exceptional laser damage threshold exceeding 1GW/cm²
- Minimal optical losses below 0.1%/cm
