The product line HarmoniXX is a series of frequency converters for ultrafast lasers, in particular for Ti: Sapphire lasers, but available for other wavelenth ranges as well. The flexible architecture of these devices allows for Second Harmonic Generation (SHG), Third Harmonic Generation (THG) and Fourth Harmonic Generation (FHG) as needed. The modular instrument design focuses on userfriendliness 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 pulse as short as sub-twenty femtoseconds. Great care has been given to the optimization of the conversion efficiency over this large pulse width range. As result these high conversion efficiencies 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 a common optical beam path of all interacting beams. It is implemented by means of a proprietary delay compensator and provides consistent spatial overlap for optimum efficiency. An additional aspect of its userfriendliness is the fact that it makes the alignment and optimization of the HarmoniXX tripler very easy and quick.
Depending on user needs and application, APE can provide two different FHG options. The fourth harmonic can be generated through repeated SHG [FHG (2+2)], which allows for a deep UV output down to 210 nm and alternatively through a SumFrequencyMixing [FHG (3+1)] for wavelengths down to 190 nm.
The Autotracker option is intended for systems with changing input wavelength. Through various integrated sensors, actuators and signal processing electronics wavelength changes are detected and subsequently the HarmoniXX is optimized using settings such as e.g. phase matching angle and crystal position.
