Beta barium borate (BaB2O4, BBO) crystal

yttrium aluminum garnet (YAG)potassium titanyl phosphate (KTiOPO4 KTP)lithium triborate (LiB3O5, LBO)

NLO Crystals NLO(Nonlinear) Crystals, means the crystals that can generate nonlinear optical effect from laser beam or electricity, magnetic field and strain field. Product Description Highly recommended NLO Crystals list from Yutai Optics: LBO, BBO, KTP, KTA, KDP, LiNbO3, MgO: LiNbO3. LBO (Lithium Triborate) crystals are excellent nonlinear crystal. For frequency doubling(SHG), tripling(THG) of Nd: YAG, Nd: YLF, Nd: YVO4 lasers, it is one of the most useful nonlinear optical materials in ultraviolet and visible laser applications. BBO (Beta-Barium Borate)crystals are important nonlinear optical crystals with combination of unique optical properties.Broad transmission and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity provide attractive possibilities for various nonlinear optical applications. KDP and DKDP (Potassium Dihydrogen Phosphate and Potassium) are one of the most widely-used commercial NLO materials, characterized by good UV transmission, high damage threshold, and high birefringence, though their NLO coefficients are relatively low. They are usually used for doubling, tripling and quadrupling of a Nd: YAG laser under the room temperature. In addition, they are also excellent electro-optic crystals with high electro-optic coefficients, widely used as electro-optical modulators, such as Q-switches, Pockels Cells, etc.
