Dia 5*15 Mm Single Crystal TGG Rods Terbium Gallium Garnet

Dia 5*15 mm Terbium Gallium Garnet Single Crystal TGG Rods for magneto-optical devices

Introduction :

Terbium gallium garnet (Tb3Ga5O12, TGG) is a crucial category of magneto-optical materials for use in the visible and the near-infrared spectral regions((400-470nm and 500-1500nm)). The TGG crystal possesses a large Verdet constant (35 RadT−1m−1 at 1064 nm), high thermal conductivity (7.4 Wm−1K−1), low optical losses (< 0.1%/cm), and high laser damage threshold (> 1 GW/cm2). Therefore, it is an attractive Faraday-rotating crystal suitable for constructing magneto-optical isolators, magneto-optical switches, magneto-optical modulators, and so on, widely used in YAG, Ti-doped sapphire, and other multi-stage amplification, ring type, seed injection laser.
