Terbium Gallium Garnet(TGG) Crystal
· TGG is an excellent magneto-optical crystal used in various Faraday devices(Polarizer and Isolator) in the range of 400nm-1100nm, excluding 475-500nm.· Faraday polarizer is composed of the TGG crystal rod and a special designed magnet. The polarization of the beam through the magneto-optical materials deflexes and direction of the deflection only has some relations with the direction of magnetic field and has nothing to do with the direction of the beam propagation. Optical isolator is an optical component which allows the transmission of polarized light in only one direction.· Basic properties:· Chemical Formula Tb3Ga5O12· Lattice Parameter a=12.355Å· Growth Method Czocralski· Density 7.13g/cm3· Mohs Hardness 8.0· Melting Point 1725 ℃· Refractive Index 1.954 at 1064nm· TGG specifications HG supply:· Standard TGG Rod Specification:· Orientation [111] within ±15 arc min· Wave Front Distortion 30dB· Diameter +0.00mm/-0.05mm· Length +0.2mm/-0.2mm· Chamfer 0.10mm @ 45°· Flatness
· Diffusion Bonded Crystals consist of one laser crystal and one or two undoped material. They are combined by optical contact method and further bonded under high temperat
· Neodymium doped Gadolinium Orthovanadate (Nd:GdVO4) is an excellent laser crystal. This crystal is ideal laser host material for the DPSS (Diode pumped Solid State) micro/m
· Neodymium Doped Yttrium Aluminum Garnet (Nd:YAG) with high efficiency, high beam damage threshold and good heat conductivity, has been applied to activate and sensitize ion
