HarmoniXX DFG

Harmonic Generation systems for Ultrafast Lasers.

The HarmoniXX DFG unit is designed to convert 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 ... > 15 μm using different crystal sets.

The HarmoniXX DFG unit consists of the beam overlap and delay module, matching the particular OPO, the frequency mixing stage, and the wavelength separation. The output is very stable benefitting from the fact that the OPO output pulses are intrinsically jitter-free. 

In alignment mode, the use of a built in PSD (position sensitive diode) allows for easy finding of the beam and pulse overlap of the two pump beams.

The DFG is available for femtosecond and picosecond OPOs of different wavelength ranges.
