10x10mmt Terbium gallium garnet (TGG)crystals substrate wafer for laser device
Product Type: Terbium gallium garnet (TGG) crystal substrateProduct Description:TGG crystal with a large magneto-optical constants, low optical loss, high thermal conductivity and high laser damage threshold, widely used YAG, Ti-doped sapphire and other multi-stage amplification, ring, seed injection lasers. Faraday rotator is used to produce the best isolator optical materials for wavelength of 400-1100nm (not including 470nm-500nm). TGG Faraday rotator by a crystal rod and a special designed magnet. Magneto-optical material through the polarization direction of the light beam in the magnetic field deflects the direction of the deflection direction of the magnetic field only, the beam propagation direction.Optical isolator consists of a 45 ° deflection of the optical device and a pair of polarizers placed in suitable composition, which the beam in one direction only through, while blocking the reverse-propagating light beams.Technical parameters:

Read before inquiry:
1. If you want to customize,you need to tell me what types do you need. Such as YAG,TGG,GGG and GAGG etc. And the materials, growth direction, related parameters and what you will use it for are also very important information we need to know.
2.There are many kinds of products in our products. The parameters of each product are different. If you want to know any crystal materials, we can provide detailed information. For you to choose.
