LT (LiTaO3) Lithium Tantalate Crystals – Electro-optic Crystal – Customized Products
LiTaO3 crystals, also known as lithium tantalate crystals, or LT crystals for short, are electro-optical crystals with excellent overall performance. LiTaO3 crystals have the advantages of high optical damage threshold, low birefringence, transmission bandwidth, high optical transmittance, high sensitivity, wide transparency range, large electro-optical coefficient, no easy deliquescence, and stable chemical and physical properties, and are used in optical storage, transient recording, high-speed holographic cameras, and other related fields. It has a wide
range of applications in related fields such as optical storage, transient recording, high-speed holographic cameras, etc. With the increasing Li/Ta in LT crystals, its physical properties are also improved to different degrees, which is conducive to improving the performance of various functional devices and making them used in many important fields such as laser TV, laser ranging, radar, infrared military countermeasures, medical treatment, and atmospheric environment monitoring, and it is likely to open up new application fields.
