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.
