Terbium gallium garnet (TGG), Tb 3 Ga 5 O 12, is a Faraday rotator material with excellent transparency properties and is very resistant to laser damage. TGG can be used in optical isolators for laser systems, in optical circulators for fiber optic systems, in optical modulators , and in current and magnetic field sensors.
Terbium gallium garnet (TGG) is a kind of synthetic garnet, with the chemical composition Tb 3 Ga 5 O 12. [1] This is a Faraday rotator material with excellent transparency properties and is very resistant to laser damage.
Tsavorite or tsavolite is a variety of the garnet group species grossular, a calcium-aluminium garnet with the formula Ca 3 Al 2 Si 3 O 12. [2] Trace amounts of vanadium or chromium provide the green color.
Colophonite, less commonly kalophonit (from Ancient Greek: κολοφωνία, kolophonia, rosin or rosin colors) — an obsolete historical name for a brownish calcium-iron mineral of the garnet family, a variety of grossular (later, andradite), discovered as an associated metamorphic mineral in the iron ore mines of the southern Norwegian islands, primarily Tromø (near Arendal).
Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP [ 2 ] ) in a hexagonal or an orthorhombic, perovskite -like form, and the monoclinic Y 4 Al 2 O 9 (YAM [ 3 ] ).
