From Extreme Nonlinear Optics to Ultrafast Atomic Physics
Prof Anne L'Huillier, Department of Physics, Lund University, Sweden
The interaction of atoms with intense laser radiation leads to the generation of high-order harmonics of the laser field. In the time domain, this corresponds to a train of pulses in the extreme ultraviolet range and with attosecond duration. This presentation will introduce the physics of high-order harmonnic generation and attosecond pulses and describe recent developments including multicolor schemes or noncollinear geometries. After the first decade where attosecond pulses were characterized, analyzed and used in –mostly– demonstration experiments, we begin to perform experiments where these pulses allow us to explore new physics. We will describe some of these applications, and in particular recent results concerning single and double photoionization dynamics.
The Distinguished Lecturer Series (DLS) follows a colloquium format for a broad audience and will be followed by a reception to provide an opportunity for meeting the speaker.
