The APE HarmoniXX Series Harmonic Generators are frequency converters for ultrafast lasers. Built as a modular system, it is ideal for picosecond and femtosecond Ti:Sapphire lasers, as well as many other sources, covering the SHG, THG, FHG and also DFG ranges to reach the UV, VIS and mid-IR wavelengths.
The HarmoniXX product line is a series of frequency converters for ultrafast lasers. Built as a modular system, it is ideal for Ti:Sapphire lasers as well as many other wavelength ranges, covering Second Harmonic Generation (SHG), Third Harmonic Generation (THG), Fourth Harmonic Generation (FHG), and Difference Frequency Generation (DFG).
In addition to precise motor control on all critical adjustable parts, the Harmonic Generation series features a special walk-off compensation mechanism, designed for highest stability and an unprecedented level of wavelength optimization. The integrated walk-off compensation design ensures constant pointing stability and enables an enhanced conversion efficiency and beam quality while changing the wavelength of the HarmoniXX. The assembly set consists of entangled crystal movement compensators for a perfect crystal match in all experimental conditions.
A flexible design, with a quick optics exchange for greater utility, allows the HarmoniXX to be configured for different laser types or alternative wavelength combinations and pulse durations. The quick-exchange optics are color-coded for a simple assignment of the different crystal types.
