Abstract

The High-Repetition-rate laser-driven Gas-based High-order Harmonic Generation (HR GHHG) beamlines of the Extreme Light Infrastructure Attosecond Light Pulse Source (ELI ALPS) have started their operation in the recent years. Both beamlines, one designed for gas-phase targets – the HR GHHG Gas beamline –, and one for condensed-phase samples – the HR GHHG Condensed beamline –, now provide high-flux, extreme ultraviolet (XUV) radiation with pump-probe capabilities at 100 kHz repetition rate. The HR GHHG Cond beamline is equipped with a time-compensated XUV monochromator, allowing for tuning the spectral properties while maintaining short, close to Fourier-limited pulse duration in the femtosecond regime. Cutting-edge experimental end stations are also available, for example a Reaction Microscope and a NanoESCA device. Both beamlines are past their first commissioning user experiments. In this presentation the capabilities along with some recent developments and latest experiments will be presented for these two unique attosecond sources.
