Covesion crystals are available off the shelf for a wide array of nonlinear interactions. Our standard crystal layout has the following features:
• Standard crystal thicknesses of 0.5 or 1.0mm
• Multiple gratings per crystal with a square aperture
• Each grating has a different period allowing temperature and/or wavelength tuning
• Crystals available in a range of lengths from 0.5 to 50mm, suitable for femtosecond to CW sources
• All crystals supplied mounted in clips for easy handling and quick mounting into a temperature controlled
Covesion oven

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 ±5 minutes, 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.
