Our aim is to perform attosecond pump probe experiments with coincidence detection of photoelectrons and -ions in a reaction microscope. To increase the data-rates we have recently developed a NOPA based OPCPA laser system providing 190 uJ laser pulses at 100 kHz repetition rate [1]. Here we discuss the laser system, pulse compression to near single-cycle duration, and spatio-temporal pulse characterization. We show high harmonic generation up to 50 eV driven by sub-3-cycle CEP stable laser pulses at 100 kHz. We discuss our recent progress towards a complete attosecond pump-probe beamline coupled to a reaction microsocpe (COLTRIMS).
