SYRP 1.3: Invited Talk

Multidimentional attosecond spectroscopy — •Nirit Dudovich — Weizmann Institute of Sceince

Attosecond science is a young field of research that has rapidly evolved over the past decade. Performing time-resolved measurements with attosecond precision is a significant challenge. Currently, two main approaches have been successfully demonstrated. The first approach, Attosecond Pump-Probe Spectroscopy, applies an attosecond pulse to initiate or probe a fast-evolving process. An alternative approach, Attosecond Self-Imaging, applies the attosecond production process, to perform the measurement. In the talk I will describe a new measurement scheme in which we integrate the two main branches in attosecond spectroscopy. In this scheme extreme ultraviolet attosecond pulses initiate an electron wavepacket by photo-ionization, a strong infrared field controls its motion, and finally electron*ion collision maps it into re-emission of attosecond radiation bursts. Our measurements resolve the internal clock provided by the self-probing mechanism, probing the photoionization the build-up of photo-ionization in the presence of the strong laser field.
