Abstract: We measured the spectral flux of the Class 5 Moonlander high harmonic generation source for two driver systems using similar pulse parameters, but at different central wavelength: a solid state multipass cell compressed Yb laser and an optical parametric amplifier system. Both laser systems provide 17W average power at 100kHz repetition rate at comparable pulse durations, 29fs vs 20fs FWHM. Main difference is the central wavelength of 1030nm for the MPC system versus the OPCPA system with a central wavelength of 800nm. We performed high harmonic generation in with both laser systems in Argon and Krypton gas media producing broad-band XUV radiation ranging from 20 to 60 eV photon energy. Using a spectrometer and an XUV diode the spectral photon flux after filtering was determined. For both systems we could reach state-of-the-art performance with photon flux of 1e11 photons/s/eV to 1e13 photons/s/eV after filtering at the output of the light source. We will discuss the advantages and disadvantages of the different drivers for the high harmonic generation.
