Product Description
Product Overview
High-precision Lithium Niobate (LiNbO3) wafers with exceptional surface roughness of Ra ≤1nm, available in 4", 6", and 8" diameters. Offered in both optical grade and SAW (Surface Acoustic Wave) grade configurations with customizable doping options.
Material Properties & Applications
Lithium niobate is transparent across the 0.25 to 5.3 μm wavelength range, making it suitable for visible, near-IR, and mid-IR applications. As a ferroelectric material, it exhibits superior piezoelectric, nonlinear optic, photoelastic, and Pockels effects with coefficients significantly higher than comparable materials.
Key Application Areas
- Electro-optical modulators and Pockels cells for laser Q-switching
- Non-linear optical devices including parametric oscillators and amplifiers
- Second harmonic generation for Nd:YAG lasers (1.064 μm) and semiconductor lasers (1.3-1.55 μm)
- High-power laser applications using MgO-doped crystals for enhanced laser damage threshold
