# Lithium tantalate, LiTaO3

Lithium Tantalate (LiTaO3) is a crystalline compound known for its unique electro-optical, piezoelectric, and pyroelectric properties. As a result of these characteristics, LiTaO3 has become highly sought after in various applications. It is often used in non-linear optics for frequency doubling of lasers, and its acoustic properties make it an attractive material for surface acoustic wave (SAW) devices. Moreover, LiTaO3 is widely used in the fabrication of acoustic wave filters in telecommunications. The crystal can also serve as a substrate for the growth of other materials in research and fabrication applications. One of the standout properties of LiTaO3 is its ability to modulate light, making it a key player in modern electro-optical modulators. While handling, it is important to be aware of the potential hazards associated with lithium compounds; thus, proper safety protocols should be followed. Optically, the crystal's refractive properties are essential for numerous photonics applications.
