Moonlander HHG

EUV source & pump-probe suite
  • 21-50 eV photon energy with optional filtering and focusing
  • full pump-probe suite available
  • 100 kHz, 200 kHz, 1 MHz rep rate version available
  • designed for ARPES and CDI


High photon flux at high repetition rate

The Moonlander HHG is an efficient coherent EUV source for time-resolved spectroscopy such as ARPES.

Driven by our high-power laser technology, the Moonlander HHG provides high photon flux at high repetition rates in a compact and robust design.

A second, synchronized optical output from UV to mid-IR can be provided with a tunable OPCPA, hence offering a full pump-probe suite to take the next step in time-resolved photoelectron spectroscopy.

Do you offer HHG-sources with higher photon energies, e.g., 92 eV?

Yes, please contact our sales team for customized solutions.

Do you provide a filtering scheme to filter single harmonics?

Yes, we can provide this in our filtering section based on the user’s needs.

Do you also provide the driver laser for the HHG source?

Yes, a laser driver is already included. Based on the user’s HHG requirements we decide on the best design in terms of laser driver.
