Lithium Tantalate (LiTaO3) possesses a combination of unique electro-optical, piezoelectric and pyroelectric properties with good mechanical and chemical stability, wide transparency range (0.4 – 5.0 µm) and high optical damage threshold.
Lithium Tantalate is a widely used electro-optical material. Its optical, electro-optical and non-linear optical properties are similar to Lithium Niobate (large effective non-linear, electro-optic and acousto-optic coefficients), but Lithium Tantalate possesses higher damage threshold (> 500 MW/cm2 for ns pulsed).
Lithium Tantalate is commonly used in non-linear optics, electro-optical modulators, pyroelectric detectors, passive infrared sensors such as motion detectors, terahertz generation and detection, cell phones and possibly pyroelectric nuclear fusion.
Typical Applications/Devices for Lithium Tantalate products:
SAW (surface acoustic wave) devices
