Our sum-frequency (SFG)/difference-frequency (DFG) MgO:PPLN crystals can be widely used for sum-frequency or difference-frequency conversion of laser wavelengths. The cycle can be designed according to the required wavelength and operating temperature, and can be used between 25-200°C. They can be used in intracavity or extracavity scenarios.
