Product description
G&H’s Periodically Poled Lithium Niobate (PPLN) crystals with 30.0–31.2 µm poling periods and a 1 mm aperture are designed for efficient mid-infrared frequency conversion through quasi-phase matching. These poling periods are ideal for difference frequency generation (DFG), sum frequency generation (SFG), and optical parametric oscillation (OPO) using near-infrared laser sources.
The larger 1 mm aperture accommodates higher optical power and broader beam profiles, enhancing throughput while maintaining high conversion efficiency.
Each crystal is fabricated with precise domain inversion and optical quality to ensure reliable integration into advanced laser and photonic systems.
Phase matching over very long propagation lengths is possible with our congruently grown PPLN manufactured from highly uniform Z-axis wafers.
