Piezoelectric Wafer Lithium Niobate LiNbO3 5mol Percent MgO Doped Wafers Designed for Acousto Optic Devices and SAW Filters
For cutting-edge technologies demanding enhanced performance and reliability, our 5mol% MgO-Doped Lithium Niobate (LiNbO₃) Wafers are engineered to deliver superior electro-optic, acoustic, and nonlinear optical properties. Ideal for high-speed optical modulators, frequency converters, SAW/BAW devices, and quantum optics, these wafers combine the exceptional characteristics of LiNbO₃ with magnesium oxide (MgO) doping for unmatched stability and efficiency.
MgO doping significantly reduces photorefractive damage, enhances thermal stability, and improves optical damage resistance, enabling operation at higher power levels without performance degradation. Our wafers feature excellent transparency (0.35–5 μm wavelength range), high electro-optic coefficients (r₃₃ ≈ 30 pm/V), and precise crystal orientation control (e.g., X-cut, Y-cut, Z-cut) for tailored applications.
Available in custom diameters, thicknesses, and surface finishes, our 5mol% MgO-doped LiNbO₃ wafers meet stringent industry standards for flatness, roughness, and purity. Whether for research, telecommunications, or advanced sensing, these wafers provide a cost-effective, high-performance solution.
Step into the future of photonics—choose our MgO-doped LiNbO₃ wafers for unparalleled precision and durability. Contact us today to request a quote or discuss your project needs!
