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