"Attosecond light synthesis: New routes to PHz nonlinear control of matter"

Real-time control of electrons in the microcosm calls for electromagnetic forces confinable and tunable over sub-femtosecond time intervals. I will discuss how recent progress in lightwave technologies has enabled key steps towards this essential milestone in science and technology. With novel types of light synthesizers which can manipulate ultrawideband coherent radiation sources, spanning the visible and flanking spectral ranges, it is now possible to sculpt and trace the waveform of light with subcyclic precision opening up the route to attosecond photonics. We will focus on first representative applications that highlight the emerging capabilities.
