LiNbO3 crystal
Lithium niobate (LiNbO3) crystals supplied by Baijing are widely used for frequency doubling at wavelengths of 1000nm or more, optical parametric amplification pumped at 1064nm, and quasi-phase matching. LiNbO3 is also used in optoelectronic modulators, waveguide materials, and Q-switches for Nd:YAG, Nd:YLF, and Ti-doped sapphire lasers. Lithium niobate is among the most commonly used materials for Q-switches, phase modulators, waveguide substrates, and surface-acoustic-wave (SAW) wafers. Iron-doped lithium niobate (LiNbO3, LN) is an excellent photorefractive material with high photorefractive sensitivity, electro-optic coefficient, and diffraction efficiency, plus excellent chemical and mechanical properties. Fe:LiNbO3 crystals are grown by the Cz method, allowing large crystals, with dopant content adjusted to specific application needs. Fe:LiNbO3 is easy to process, inexpensive, and suitable for mass production.
