Harmonic Generation



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.

At a Glance

  • Fourth Harmonic Generation FHG
  • High conversion efficiency
  • Easy alignment and automatic wavelength tuning
  • Suitable for both tunable and fixed frequency fs and ps lasers
  • Excellent pointing stability and beam profile
  • Remote operation via software GUI
