High-Temperature-Phase Barium Borate (α-BBO)
High-temperature-phase barium metaborate is an important optical-crystal product from Ketong. This negative uniaxial crystal exhibits large birefringence over its 189nm to 3500nm transmission range. Ketong has successfully grown large crystals whose physical, chemical, thermal and optical properties closely resemble low-temperature-phase barium metaborate. Centrosymmetry eliminates its nonlinear optical properties, so it is generally not used for nonlinear processes.

KDP is potassium dihydrogen phosphate. Potassium dideuterium phosphate (DKDP) has a relatively low nonlinear coefficient, but excellent ultraviolet transmission, a high damage threshold, and high birefringence support widespread industrial use. Both crystals are commonly used for second-, third-, and fourth-harmonic generation of Nd:YAG lasers at room temperature. Their high electro-optic coefficients also support Q-switches and Pockels cells.

Chemical Formula [Fe-doped Fe:LiNbO3 subsection]: Fe：LiNbO3 Crystal Structure [Fe-doped Fe:LiNbO3 subsection]: Triangular, 3m Density [Fe-doped Fe:LiNbO3 subsection]: 4,64
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.
