Highlight: | TGG Terbium Gallium Garnet,Dia 100mm Magneto Optical Crystal,Optical Terbium Gallium Garnet |
Terbium gallium garnet (TGG) is a kind of high performance magneto-optical crystal in the visible and near infrared spectrum, which is widely used in laser technology, optical communication and optical information processing technology. It has high feld constant, low optical absorption coefficient, high laser damage threshold and good optical properties. These excellent properties make TGG crystal an ideal material for magneto-optical isolator.
In recent years, growing large-size and high-quality TGG crystals has been a hot research topic in the field of crystal materials at home and abroad. With the unremitting efforts of the professional R & D team, Corus has successfully grown TGG crystal with a diameter of 100 mm in June 2020.
