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.

Ytterbium-doped Potassium Gadolinium Tungstate (Yb:KGd(WO₄)₂, Yb:KGW) crystal is an excellent laser gain material, boasting numerous advantages over the widely used Nd³⁺-doped materials. Its wide spectral emission band of 1023-1060 nm enables the generation of short laser pulses (picosecond or femtosecond level). The broad absorption band at 980 nm and highly absorbent pump radiation allow it to efficiently utilize diode laser pumping. Compared with YAG doped with Yb³⁺ ions, KGW crystal has a larger absorption cross-section, which reduces the minimum pump intensity required to achieve transparency in the quasi-two-level system of Yb.
