Lithium tantalate (LiTaO3) Nonlinear Optical Grade Crystal Wafer
Lithium Tantalate (LT, LiTaO3) has unique properties, which as a
material finds uses in Electro-Optical and Acousto-Optical
applications. These can be : surface acoustic wave devices, bulk
acoustic wave devices, piezo-electric transducers and piezoelectric
sensors.The 36° and 42 ° cuts of Lithium Tantalate have shown
widespread adoption for the telecommunications mobile phone handset
market at frequencies from 800 to 2100 MHz. These orientations show
an optimized bandwidth / insertion loss trade off in performance
and are dominating the ever expanding mobile handset sales.
Crystro's LiTaO3 lithium tantalate crystal has >99.99% purity. Find
high-quality lithium tantalate bulk crystals, wafers and substrates
Crystro's LiTaO3 crystal is grown by Czochralski method.Max diameter reach 4inch,it's now the biggest size in this filed,we can custom size and specs ,rougness<0.5nm.
Other optical single crystals like GGG,SGGG,TGG,TSAG are also
available.
