Lithium Tantalate (LiTaO₃) crystal, abbreviated as LT crystal, is an electro-optic, nonlinear optical, and piezoelectric material with a trigonal crystal structure.
Product Introduction
Lithium Tantalate (LiTaO₃) crystal, abbreviated as LT crystal, is an electro-optic, nonlinear optical, and piezoelectric material with a trigonal crystal structure.
It exhibits excellent thermal stability and wide-band transmittance, boasting high optical transparency across the ultraviolet to mid-infrared spectral range. Lithium tantalate (LiTaO₃, LT) crystals demonstrate remarkable electro-optic effects, dielectric constants, and mechanical properties, making them widely used in applications such as optical communications, precision sensing, and laser technology.LiTaO₃ crystals (lithium tantalate, LT) boast several advantageous properties, including a high optical damage threshold, low birefringence, wide transmission bandwidth, exceptional light transmittance, high sensitivity, an extensive transparency range, a large electro-optic coefficient, and stable chemical and physical characteristics. These qualities make them highly suitable for applications in areas such as optical storage, transient recording, and high-speed holographic cameras. As the Li/Ta ratio in LiTaO₃ crystals continues to increase, their physical performance improves to varying degrees, further enhancing the functionality and efficiency of related devices. This advancement enables broader adoption of LiTaO₃-based technologies in critical fields like laser TVs, laser rangefinders, radar systems, infrared military countermeasures, medical diagnostics, and atmospheric environmental monitoring—while also holding significant potential for pioneering entirely new application areas.
