LiNbO3 Crystal has unique electro-optical, piezoelectric, photoelastic and nonlinear optical properties. They are strongly birefringent. They are used in laserfrequency doubling, nonlinear optics, Pockels cells, optical parametric oscillators, Q-switching devices for lasers, other acousto-opticdevices, optical switches for gigahertz frequencies, etc. It is an excellent material for manufacture of optical waveguides, etc.
Usually LiNbO3 wafer is indexed as X cut, Y cut or Z cut with trigonal structure, it also can be indexed with hexagonal structure. Conversion from the trigonal -index system to hexagonal as [u ' v ' w ' ] ---> [u v t w] is accomplished by the following formulas:
| X-cut (110) = (11-20) or (22-40) | XRD 2theta is 36.56 or 77.73 degrees |
| Y-cut (010) = (10-10),(20-20) or (30-30） | XRD 2theta is 20.86,42.46,65.83 degrees. |
