HarmoniXX DFG – Difference Frequency Generator
Advances in Optical Parametric Oscillator (OPO) Technology In an OPO the pump laser beam is split into two distinct beams - Signal and Idler. When the wavelength range of Signal and Idler is not reaching far enough into the mid-Infrared, the two beams can be mixed within the HarmoniXX DFG to significantly extend the wavelength range - even beyond 20 µm. Within APE's Difference Frequency Generator, the Signal and Idler are compressed and overlapped in time and space in a non-linear...
