64Y 128Y Cut single side polished lithium niobate crystal wafer for surface acoustic wave SAW device
Lithium Niobate has good nonlinear optical properties and can be used as optical waveguide material, or to produce medium and low frequency SAW filter, high power high temperature resistant ultrasonic transducer, etc. Lithium niobate doping is now widely used, such as Mg:LN, Nd:Mg:LN, Fe:LN.
Lithium Tantalate has good piezoelectric, ferroelectric, acousto-optic and electro-optic effects. It is widely used in resonators, filters, transducers, as well as high-frequency surface acoustic wave devices
