Piezoelectric Crystal Lithium Tantalate LT LiTaO3 crystals
Lithium Niobate (LiNbO3 or LNB) and Lithium Tantalate (LiTaO3 or LTA) possess 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. An indispensable condition of some of these applications is a
high degree of optical uniformity of Lithium Niobate crystals used
for fabrication of active elements.
Some other crystals of LiNbO3 series are available, including LiNbO3 doped with Fe, Zn, Gd, Cu , Y, B, Er etc.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.
