| Abstract: | Electron recollision in an intense laser field is at the center of attoscience research and gives rise to a variety of phenomena, ranging from the photo effect to coherent X-ray emission. We have, over the years, developed intense sources of waveform controlled mid-IR light, i.e. few-cycle duration and carrier to envelope phase stable pulses, to exploit ponderomotive scaling, quantum diffusion and quasi-static photo emission. I will describe the laser technology that enables this new direction of strong field research and our recent achievements in the generation of attosecond pulses at the oxygen K-shell edge (530 eV) and application to soft X-ray absorption spectroscopy in condensed matter. |
