Lithium Niobate Wafer
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.
