Lithium niobate (LiNbO3, LN) is a multi-purpose material in photonics and optoelectronics fields. As a highly versatile lithium niobate crystal (often referred to as an LN crystal), it features excellent nonlinear, electro-optic, and piezoelectric properties. This high-purity LiNbO3 single crystal 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. The unique LiNbO3 crystal structure allows it to perform exceptionally well in various complex optical systems.

1. What is the difference between LiNbO3 and an LBO crystal?
While both are nonlinear optical materials, an LBO crystal (Lithium Triborate) is primarily used for high-power UV and visible light generation (like SHG/THG) due to its high damage threshold. A LiNbO3 crystal excels in electro-optic modulation, Q-switching, and optical parametric oscillators (OPO) because of its broad transparency and strong electro-optic coefficients.
2. How does the LiNbO3 crystal structure affect its performance?
The LiNbO3 crystal structure belongs to the trigonal crystal system. This unique asymmetric structure is the fundamental reason behind its strong piezoelectric, electro-optic, and nonlinear optical properties, making it indispensable for modern photonics.
3. What determines the lithium niobate price?
The lithium niobate price varies based on the dimensions, specific cut angles, doping requirements (e.g., 5% MgO doped), and custom coatings (AR/HR) or electrodes required for your specific application. Contact us for a precise quote.
HGO offers both pure Lithium niobate (LiNbO3, LN) and 5% MgO doped Lithium niobate crystals for Q-switches with transverse E-O modulation, second harmonic generation (SHG), sum frequency generation (SFG), different frequency generation (DFG), or optical parametric generation (OPA). High quality LiNbO3 single crystals with λ/10 wavefront distortion can be reliably supplied by HGO.

HGO grows BBO Nonlinear crystals using flux technology. BBO crystal transparency ranges from 188 nm to 5,2 µm, which includes reasonable transparency from 3-5,2 µm for few tens µm thick crystals, while their phase-matchable range spans almost over the entire transparency range. Combined with other magnificent properties of BBO, it is favorable for numerous nonlinear parametric applications. It is worth to mention that BBO crystals have the highest nonlinearity in the UV range out of all common nonlinear crystals.

KDP Potassium Dihydrogen Phosphate and KD*P or DKDP Potassium Dideuterium Phosphate are among 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.

Non-Polarizing Cube Beamsplitters also called NPBS Cube is a more sophisticated type consisting of two right- angle prisms cemented together at their hypotenuse faces.The cemented face of one prism is coated. Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection could be designed to 10%, 20%, 30%, 40%, 50%, etc.

Sapphire window retains its high strength at high temperatures, has good thermal properties and excellent transparency. It is chemically resistant to common acids and alkali at temperatures up to 1000 °C as well as to HF below 300 °C. These properties encourage its wide use in hostile environments where optical transmission in the range from the vacuum ultraviolet to the near infrared is required.

α-BBO (α-BaB2O4) is a negative uniaxial crystal which has large birefringence over a broad transparent range of 190nm to 3500nm. α-BBO is an excellent crystal especially in UV and high power applications. The physical, chemical, thermal, and optical properties of alpha-BBO crystal are similar to those of Beta-BBO. However, there is no second order nonlinear effect in alpha-BBO crystal due to the centrosymmetry in its crystal structure and thus it has no use for second order nonlinear optical processes. Instead, alpha-BBO is widely used for fabrication of polarizers, polarizing beam displacers, phase retarders, birefringent plates, and time delay compensators especially those for UV and high power lasers.
