HarmoniXX FHG
Fourth Harmonic Generation – Frequency Quadrupling for Tunable and Fixed Frequency Laser
Fourth Harmonic Generation
As part of our HarmoniXX product line, the HarmoniXX FHG – Fourth Harmonic Generation – is a frequency converter for quadrupling the frequency of ultra short-pulse lasers. As a result, the final frequency is four times of the frequency of the incoming laser beam.
User-friendly Design
The focus is on user-friendliness and a compact design. By featuring a quick exchange of optics, the HarmoniXX devices can be used for a wide pulse duration range, from femtoseconds (fs) to several picoseconds (ps). All units are optimized for highest conversion efficiency at various laser power levels. They also display minimum pulse broadening while maintaining good spatial beam profile.
