Product Description
Descriptions:
Lithium niobate (LiNbO3, LN) is a multi-purpose material in photonics and optoelectronics fields. It features excellent nonlinear, electro-optic, and piezoelectric properties. it is widely used as electro-optic modulators and Q-switches for Nd:YAG, Nd:YLF and Ti:Sapphire lasers as well as modulators for fiber optics.
Main applications:
1) Electro-optic modulation and Q-switching
2) Optical parametric oscillators (OPO) pumped at 1064 nm
3) Quasi-phase-matched devices with periodically poled lithium niobate (PPLN)
Advantages:
1) Broad transparency region from 420 nm to 5200 nm
2) High nonlinear, electro-optic and acousto-optic coefficients
3) Nonhygroscopic, mechanically, and chemically stable
