HarmoniXX
The product line HarmoniXX is a series of frequency
converters for ultrafast lasers, in particular
for Ti:Sapphire lasers, but available for other
wavelength ranges as well. The exible architecture
of these devices allows for Second Harmonic
Generation (SHG), Third Harmonic Generation
(THG), and Fourth Harmonic Generation (FHG) as
needed. Also, a version generating the difference
frequency (DFG) from two input wavelengths is
available. The modular instrument design focuses on
user-friendliness and compactness, with automated
wavelength tuning available.
The HarmoniXX is equipped with quickly
exchangeable optics and works with an extremely
wide range of different pulse widths, it can be used
with tens of picoseconds as well as with pulses
down to 100 fs. Great care has been applied to
the optimization of the conversion efciency over
this large pulse width range. As a result these
high conversion efciencies can now be achieved
at various power levels and with minimum pulse
broadening.
Unlike conventional triplers, the new HarmoniXX
THG needs no separation and recombination of the
interacting beams. This user-friendly feature is due
to the use of one common optical beam path for
all interacting beams. It is implemented by means
of a proprietary delay compensator and provides
consistent spatial overlap for optimum efciency.
