It can be made into various acousto-optic devices, such as acousto-optic deflectors, acousto-optic Q-switches, surface acoustic wave devices, etc., so that these crystals are widely used in lidar, scanning of TVs and large-screen displays, and optical computers in photonic computers. memory and laser communication.
Laser emission at 1.5μm is very effective for some industrial applications. This is primarily due to the eye safety of 1.5 microns of radiation. Other advantages of this wavelength are high transparency in atmospheric and fused quartz waveguides, and availability of sensitive chamber temperature photodetectors (Ge and InGaAs photodiodes).
Terbium scandium aluminum garnet (TSAG) crystal is an ideal magneto-optical material, suitable for visible and infrared wavelengths (wavelength range: 400-1600nm). TSAG crystal has the advantages of high stability, good thermal and mechanical properties, which is essential for the next generation of high-power lasers.
Terbium gallium garnet (TGG) is a kind of high performance magneto-optical crystal in the visible and near infrared spectrum, which is widely used in laser technology, optical communication and optical information processing technology. It has high feld constant, low optical absorption coefficient, high laser damage threshold and good optical properties. These excellent properties make TGG crystal an ideal material for magneto-optical isolator.
