LiTaO3

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.

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.

TGG is an excellent magneto-optical crystal material, which is used in all kinds of Faraday isolators and rotators. The applicable wavelength is 400nm-1100nm (except 475-500nm).

Lithium Triborate LiB3O5 (LBO) crystal is an excellent frequency crystal, which is a widely used frequency doubling device.The crystal has good optical uniformity, wide penetration band, and high matching efficiency and laser damage threshold. LBO crystals have stable chemical properties, high mechanical hardness, low deliquescence and birefringence less than BBO crystals, so help to limit the phase matching spectral range.

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.
