5mol% MgO Doped LiNbO3 Wafers Optimal Material for High-Performance Optoelectronics
Our 5mol% MgO-doped Lithium Niobate (LiNbO₃) wafers represent a breakthrough in nonlinear optical and electro-optic materials, engineered to deliver superior stability and efficiency for cutting-edge applications. By incorporating 5mol% magnesium oxide (MgO) doping, these wafers significantly reduce photorefractive damage, enhance optical damage thresholds, and improve thermal stability compared to undoped LiNbO₃, making them ideal for high-power laser systems, frequency converters, and integrated photonics.
Precision-manufactured using the Czochralski method, each wafer features exceptional crystallographic quality with uniform MgO distribution, ensuring consistent performance across batches. Available in standard diameters (2" to 4") and thicknesses (0.5mm to 1mm), with customizable orientations (X-cut, Y-cut, Z-cut), these wafers meet stringent requirements for surface flatness (<λ/10), low roughness (<0.5nm RMS), and high optical transparency (>99.5% T).
Perfect for acousto-optic devices, SAW filters, and quantum optics research, our wafers are backed by rigorous quality testing and ISO-certified processes. Elevate your optoelectronic innovations with 5mol% MgO-doped LiNbO₃ wafers—where enhanced durability meets unmatched precision.
