Abstract

Electron recollision in an intense laser field is at the centre of attoscience research and gives rise to a variety of phenomena, ranging from electron diffraction to coherent soft X-ray emission. We have, over the years, developed intense sources of waveform controlled mid-IR light to exploit ponderomotive scaling, quantum diffusion and quasi-static photo emission. I will describe our recent achievements to image a molecule with one of its own electrons while a bond breaks and report on the generation of isolated attosecond pulses in the soft X-ray water window (284 - 530 eV) and how we can follow a material’s excitation in real time.
