Lithium Tantalate (LiTaO3) Crystal | Nonlinear Optical Crystal Material

Lithium tantalite (LiTaO3) is similar to lithium niobate. Both are grown by the Czochralski method which yields large, high quality single crystals. Lithium tantalate possesses unique electro-optical, acoustic, piezoelectric and pyroelectric properties, which makes it attractive for numerous applications including electro-optical modulators, pyroelectric detectors, piezoelectric transducers and sensors. It has good mechanical and chemical stability, a wide transparency range and a high optical damage threshold.

LiTaO3 crystal is also widely used E-O crystal, due to its optical, NLO and E-O poperties similar to those of LiNbO3 crystal, but with higher damage threshold (> 500 MW/cm2 for ns pulsed).
