TSAG Grade TGG Magneto-Optical Crystal 100mm Diameter for Faraday Isolators 400-1100nm
High-Grade TSAG Level TGG Magneto-Optical Crystal, Terbium Gallium Garnet for Faraday Isolators & Rotators, 400–1100nm Transmission (Excluding 475–500nm), 4 Inch TGG Boules Available from Crystro
Terbium gallium garnet (TGG) crystals are a high-performance magnetoelectric crystal operating within the visible and near-infrared spectral range. They are extensively used in laser technology, optical communication, and optical information processing. TGG crystals possess characteristics such as high Feld constant, low optical absorption coefficient, high laser damage threshold, and excellent optical properties. These favorable material properties make TGG crystals an ideal material for applications in magnetoelectric isolators. In recent years, growing large-sized, high-quality TGG crystals has been a prominent research topic in both domestic and international crystal material fields. Through relentless efforts by the development team, Corisun successfully grew a TGG crystal with a diameter of 100 mm in June 2020. The product has received international customer certification (Faraday isolator for a 100 J/10 Hz pulsed laser – Anhui Corisun Crystal Material Co., Ltd.).
