High Quality for Ln - LiNbO3 Crystal – WISOPTIC Detail:

LiNbO3 (Lithium Niobate) crystal is a multifunctional material that integrates properties of piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, etc. LiNbO3 has good thermal stability and chemical stability.

As one of the most thoroughly characterized nonlinear optical materials, LiNbO3 is suitable for a variety of frequency conversion applications. For example, it is widely used as frequency doublers for wavelength >1 μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices. Due to its large E-O and A-O coefficients, LiNbO3 crystal is also commonly used for phase modulators, waveguide substrate, surface acoustic wave wafers, and Q-switching of Nd:YAG, Nd:YLF and Ti-Sapphire lasers.

LiNbO3 can be doped with a variety of elements, such as Er, Pr, Mg, Fe, etc., which give the material unique properties. For example, the damage threshold of MgO: LiNbO3 is more than double that of pure LiNbO3.
