Product Description

LiTaO3 crystal belongs to 3m crystal system. The transverse electro-optic modulation of the crystal can be used to measure the electric field. LiTaO3 has excellent electro-optic properties, it has higher electro-optic coefficient than LiNbO3, higher optical damage threshold, lower birefringence, wide transmission band, and high light transmittance. The crystals produced by different crystal growth methods have different optical damage thresholds, the LiTaO3 crystal prepared by top-seeded solution method is one order of magnitude higher than that of the same component crystal. As an electro-optical crystal for measuring an electric field, LiTaO3 is widely used because of its large electro-optic coefficient, which makes it highly sensitive in measurement ,and the wafer fabrication cost is low.
