Neodymium-doped yttrium aluminum garnet (Nd:YAG) is the earliest and most famous and widely used laser crystal.Because of its many excellent basic properties, Nd:YAG is still often used in near-far infrared solid-state lasers and their frequency doubling and frequency doubling.

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.

Base on phase-shifting technique, the laser interferometer, widely used in the high-precision measurement of planar and spherical optical components, characterizes the three-dimensional topography of the measured surface with a precision of 0.06 μm (Peak-to-valley) or higher.

Fiber galvanometer scanner is mainly applied to the laser marking and laser welding devices.

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.

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.

TSAG is the key isolator material of the next generation fiber laser. As an ideal visible and infrared magneto-optical crystal, TSAG has the advantages of high Verdet constant, excellent thermal and mechanical properties.
