Product Description

4inch diameter 100mm Lithium niobate LiNbO3 substrate wafer, LN wafer for saw and optical,SAW Grade LiNbO3 Crystal ingot​



Lithium niobate (LiNbO3) is a ferroelectric material suitable for a variety of applications. Its versatility

is made possible by the excellent electro-optic, nonlinear, and piezoelectric properties of the intrinsic

material. It is one of the most thoroughly characterized electro-optic materials, and crystal growing techniques consistently produce large crystals of high perfection.



  • Frequency doubling for wavelengths >1μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices;

  • Pockel cells, Q-switches, and phase modulators;

  • Waveguide substrates, surface acoustic wave (SAW) wafers.
