5mol% MgO-doped LiNbO3 Wafers Nonlinear Optical and Electro-optic Materials Engineered for Superior Stability and Efficiency
Elevate your laser systems and nonlinear optical devices with our 5mol% MgO-Doped Lithium Niobate (LiNbO₃) Wafers, engineered to deliver superior photorefractive resistance and thermal stability compared to undoped variants. By incorporating 5mol% magnesium oxide (MgO), these wafers significantly reduce optical damage thresholds, enabling reliable operation under high-intensity light conditions—ideal for frequency doubling, optical parametric oscillators (OPOs), and high-power laser modulators.
Our wafers feature ultra-low defect densities, precise crystal orientation (X-cut, Y-cut, or Z-cut), and exceptional surface finishes (Ra < 0.5 nm), ensuring minimal scattering losses and optimal coupling efficiency. The MgO doping also enhances electro-optic coefficients, making them perfect for high-speed modulators in telecommunication networks.
Available in customizable diameters (2"–6") and thicknesses, our wafers meet stringent industry standards for performance and durability. Backed by ISO-certified manufacturing and rigorous quality testing, they provide a cost-effective solution for demanding applications.
Unlock next-level performance. Choose our 5mol% MgO-doped LiNbO₃ Wafers for unmatched reliability and efficiency. Contact us today to transform your optoelectronic innovations.
