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.

LiNbO₃can 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: LiNbO₃is more than double that of pure LiNbO₃.

PPLN: Periodically Polarized Lithium Niobate (PPLN) is a highly efficient wavelength conversion non-linear crystal with wide light transmission range (0.4-4.5 µm) covering the near and mid-infrared regions, long service life, and can be used for frequency doubling, beat frequency, sum frequency, optical parametric oscillation and optical parametric amplification, etc. Temperature control is required during use. The PPLN OPO process can be used to obtain light with wavelength of 3~4.5 µm, which is difficult to be achieved (as high-efficiency output) with conventional phase matching. Different wavelengths of PPLN correspond to different polarization periods.
