Phase matching curve for MDFG2-0.5-XX
Please note these are calculated tuning curves only and actual values may vary.
Key Features
The MDFG2 is designed for Difference Frequency Generation (DFG) from a Nd:YAG laser and a tunable Ti-Sapphire (or similar) lasers, for mid-IR generation in the 2.9-4.7µm range.
The output wavelength can be tuned with each PPLN grating by adjusting the input laser wavelength and varying the PPLN temperature.

PPLN Oven Mount Adapters
For easy integration into your optical arrangement, Covesion provides a flexible range of oven mounting adapters for post mounting solutions or flexure stage solutions, as well as a small compact mount for oven-free arrangements.
Temperature Controller
For high stability temperature control, the Covesion OC2 is a compact stand-alone bench-top unit for use with our PPLN oven range.
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.
