Magnesium-doped Periodicaly Poled Lithium Niobate (MgO:PPLN) offers high efficiency wavelength conversion for visible and mid-infrared applications. Adding 5% Magnesium-Oxide to Lithium Niobate significantly increases the optical and photorefractive resistance of the crystal while preserving its high nonlinear coefficient. This allows more stable operation at visible wavelengths and lower temperature operation than a similar undoped crystal. Specially developed for Red-Green-Blue (RGB) generation and high power Mid-IR operation, our proprietary MgO:PPLN poling process offers high quality material even at shorter periods.
Our proprietary Magnesium-doped PPLN poling process creates high fidelity periods from 4.5μm to 33μm+ and is ideal for volume manufacture. As shown above, our MgO:PPLN domains are poled through the entire thickness of the sample, providing maximum optical aperture.
Standard PPLN Crystal Layout
Each MgO:PPLN crystal includes multiple gratings for flexible temperature and wavelength operation. Our crystals are AR coated and polished to: <λ/4 flatness, parallel to ±5minutes, with better than 20-10 scratch-dig and fewer than two 100μm edge chips per facet. All of our Magnesium-doped PPLN products undergo rigorous quality inspection, are supplied clip-mounted off-the shelf and are fully compatible with our range of PPLN accessories.
Custom crystal lengths, thicknesses, AR coatings, and grating designs are also available on request.

PPLN Ovens
For fixed wavelength applications PPLN should be maintained at a constant operating temperature for maximum conversion efficiency. In tunable wavelength applications the temperature of the crystal can be adjusted for fine wavelength tuning.
