Product Description
Piezoelectric Lithium Niobate Wafer Overview
Lithium niobate is a versatile ferroelectric material with exceptional optical and piezoelectric properties. It offers transparency across 0.25-5.3 μm wavelengths and demonstrates superior coefficients for various effects including piezoelectric, nonlinear optic, photoelastic, and Pockels effect.
Key Applications
- Optical amplitude and phase modulators
- Pockels cells and laser Q-switching modulators
- Optical parametric oscillators and amplifiers
- Second harmonic generators for Nd:YAG lasers (1.064 μm)
- Semiconductor laser applications (1.3 and 1.55 μm)
For high-power laser applications, magnesium oxide-doped crystals (MgO:LiNbO3) are recommended due to their higher laser damage threshold while maintaining optical properties.
