Faraday rotator is based on the nonreciprocity of magneto-optical materials, that is, it can rotate the polarization planes of the normal incident light and the reverse incident light of the same wavelength to the same direction and the same angle, independent of the beam propagation direction. If a Faraday rotator with 45 degree rotation of the polarization plane of the incident beam is placed between a pair of polarizers orthogonal to each other to form an optical isolator, it only allows the forward propagating beam to pass through the system and blocks the backward propagating beam. Faraday rotator is an important component of optical isolator, which is widely used in various laser systems, such as multi-stage laser amplifier, optical parametric oscillator, ring laser, erbium-doped fiber amplifier, seed injection laser, optical switch, optical modulator and so on.

LiTaO3 is an important multifunctional crystal material with excellent piezoelectric, ferroelectric, acoustooptic and electro-optic effects. LiTaO3 has been successfully used in many devices and equipment, especially in electro-optic devices, infrared detectors and surface acoustic wave devices.

Der Lithiumtriborat-LiB3O5 (LBO)-Kristall ist ein ausgezeichneter Frequenzkristall, der ein weit verbreitetes Gerät zur Frequenzverdopplung ist. Der Kristall weist eine gute optische Gleichmäßigkeit, ein breites Durchdringungsband sowie eine hohe Anpassungseffizienz und Laserzerstörschwelle auf. LBO-Kristalle haben stabile chemische Eigenschaften, eine hohe mechanische Härte, geringe Zerfließen und eine geringere Doppelbrechung als BBO-Kristalle und tragen so dazu bei, den Phasenanpassungsspektralbereich einzuschränken.

Sggg crystal, namely Ca Mg Zr doped gadolinium gallium garnet, is an excellent substrate material for Bi Fe garnet epitaxial films.

Cerium doped Lutetium Aluminium Garnet (Ce:LuAG) is a well-established scintillator and has many attractive properties, such as fast decay (80ns),high light yield, emission peaks at 510nm that well matched with the sensitivity of commercial Si-CCD detectors as well as good mechanical and chemical stability. Ce:LuAG is also a very appropriate crystal for imaging screens, LED lighting and laser lighting.

Ce:GAGG is a relatively new single scintillation crystal with many properties, such as high light yield, high density, good energy resolution, good emission peak matching with silicon sensor and low intrinsic energy resolution. in addition, the material is non-hygroscopic and non-self-radiative. which is widely used in PET, PEM, SPECT, CT, X and Y ray detection and so on.
