Fe+ doped LiTaO3 Single Crystal Wafers
Introduction:
Lithium tantalate (LiTaO3, LT) optical grade crystal is multifunctional crystal material. LT crystal integrates multiple effects such as piezoelectric, electro-optics, Acousto-Optical, and nonlinear optics. It is an excellent material for sound transmission medium and high-frequency transducers. It can be widely used in electro-optical devices, laser frequency doublers, Acousto-Optical devices, etc.
The 36° and 42 ° cuts of Lithium Tantalate have shown widespread adoption for the telecommunications mobile phone handset market at frequencies from 800 to 2100 MHz.
