We use reduction technique to produce pyroelectric free black LiNbO3 wafers, which has a high ability to neutralize charges even if the electric potential occurs instantaneously. The pyroelectric effect of black LiNbO3 wafers is almost eliminated and the transmittance is significantly reduced. The piezoelectric properties of black lithium niobate wafers are no different from those of standard wafers. Therefore, black reduced lithium niobate wafers are widely used to produce higher frequency surface acoustic wave devices.
LiNbO3 wafers can be used to manufacture Q-switching devices, high-performance gyroscope, accelerators and accelerometer sensors, MEMS devices, surfaced acoustic devices and so on.
