Key Features

The MDFG3 is designed for Difference Frequency Generation (DFG) from a 1064nm laser and a tunable 1480-2128nm source, for mid-IR generation in the 2.1-3.8µm range.

The output wavelength can be tuned with each PPLN grating by adjusting the input laser wavelength and varying the PPLN temperature.
