HarmoniXX Select SHG
Pulse Picking & Second Harmonic Generation Combined
Combined Solution for Pulse Picking & Second Harmonic Generation
Pulse Picking and SHG with HarmoniXX Select SHG
HarmoniXX Select is the combination of two well-known APE products in one box: Adjusting the repetition rate by pulse picking (pulseSelect) + second harmonic wavelength conversion (HarmoniXX SHG) of modelocked lasers. The on-board pulse picker with its low dispersive design is developed for requirements associated with ultrashort pulse laser technology. The integrated second harmonic generator features frequency doubling of the picked input laser beam. With its flexible design, the HarmoniXX Select SHG can be adapted to Ti:Sa lasers or other broadly tuneable lasers, such as Coherent Discovery or Spectra Physics Insight.
