LiTaO3 crystal
Product name : LiTaO3 crystal
Item : 010
Details :

Lithium Tantalate (LiTaO3 or LT) possesses a combination of unique electro-optical, acoustic, piezoelectric, pyroelectric and non-linear optical properties, making it a suitable material for applications in acoustic, electro-optical and non-linear optical devices, high-temperature acoustic transducers, receivers-transmitters of acoustic vibrations, air force acceleration meters, acoustic wave delay lines, deflectors, generators of non-linear distorted waves, acoustic filters, electro-optical Q-modulators (Q-switch), encoders-decoders, filters in television receivers, video-recorders and decoders, converters, frequency doublers and resonators in laser systems, non-linear elements in parametric light generators, etc. Crystal growth technology by low temperature-gradient Czochralsky method allows the growth of large-size high-quality LNB (up to 1-1.5 kg) and LTA single crystals for such non-conventional applications. It should be noted that both crystals are non-hygroscopic, colourless, water-insoluble and have low transmission losses.


For some applications similar in properties to Lithium Tantalate (LiTaO3) crystal is more advantageous than LiNbO3 (E-O modulators, pyroelectric sensors etc.). Lithium Tantalate exhibits unique electro-optical, pyroelectric and piezoelectric properties combined with good mechanical and chemical stability and wide transparency range and high optical damage threshold. This makes LiTaO3 well-suited for numerous applications including electro-optical modulators, pyroelectric detectors, optical waveguide and SAW substrates, piezoelectric transducers etc. MolTech can offer parts cut from high quality boules grown along X axis, fully poled, with dia. and length of up to 60 mm.
