DFG


Wavelength Conversion

APE offers an exceptional conversion range that covers frequency doubling, tripling and quadrupling. All with a modular structure that makes upgrading simple. Also, a version generating the difference frequency (DFG) from two input wavelengths is available.

DFG

The HarmoniXX DFG (Difference Frequency Generation) converts the output of a synchronously pumped OPO into the Mid IR range by mixing Signal and Idler output beams. The DFG output wavelength can be changed easily when tuning the OPO Signal. It covers a wide wavelength range of 4 ... > 10 µm.
