Product description
G&H’s Periodically Poled Lithium Niobate (PPLN) crystals with poling periods of 30.0–31.2 µm and a 0.5 mm aperture are optimized for quasi-phase-matched nonlinear frequency conversion in the mid-infrared range.
These grating periods are suited for difference frequency generation (DFG), sum frequency generation (SFG), and optical parametric oscillation (OPO) when paired with near-IR pump sources. The 0.5 mm aperture supports compact system integration while maintaining precise optical alignment and conversion efficiency.
Fabricated to strict optical and domain uniformity standards, these crystals enable stable, high-performance operation in advanced photonic and laser systems.
Phase matching over very long propagation lengths is possible with our congruently grown PPLN manufactured from highly uniform Z-axis wafers.
