HarmoniXX DFG
The HarmoniXX DFG unit is designed to extend
APE's product line of wavelength converters
into the Mid IR range. It mixes Signal and Idler
output beams of synchronously pumped OPOs
and is available for various pump sources.
The DFG output wavelength can be changed
easily by tuning the OPO Signal. It covers a wide
wavelength range of 4 ... > 15 μm.
The HarmoniXX DFG unit has an integrated
wavelength separation for maximum userfriendliness. The output is very stablebenefitting from the fact that the OPO outputpulses are intrinsically jitter-free.
The DFG is available for femtosecond andpicosecond OPOs of different wavelengthranges.

• High power and conversion efficiency• Easy wavelength tuning• Flexible architecture for fs / ps input

Versions and Applications
The HarmoniXX DFG is available in different versions, depending on the pump source and the pulsewidth.
The picosecond version can be pumped by pulses with 2 … 6 ps pulse width and is able to reachwavelengths from 4.8 ... 15 μm. It is optimized for high resolution measurements and pulses with narrow
bandwidth. Therefore it is perfect for Sum Frequency Mixing Spectroscopy.
The femtosecond version of the HarmoniXX DFG delivers short pulses with broad spectral bandwidth in
the MIR. The standard version can be tuned from 4 ... 11 μm. An optionally available Optics Set extends
the wavelength range to 10 ... > 15 μm. The HarmoniXX DFG fs is especially suitable for applications that
require high time resolution such as fs s-SNOM.
