Attosecond correlation spectroscopy and coherent control of molecular dissociation
Attosecond pulses (1as=10-18 s) are the shortest events available with state-of-the-art laser technology. They have been used in several laboratories for the investigation of fundamental electronic processes, which evolve, typically, on a comparable timescale. A prerequisite for attosecond spectroscopy is a reliable characterization of the temporal structure of the attosecond waveforms. This task requires the development of ultrastable interferometer, in which the relative delay between the two arms is controlled within a resolution below few tens of attoseconds. This approach works for table-top sources, but it is not applicable at free electron lasers, due to their large dimensions and complexity. This limitation represents a major obstacle to the advancement of attosecond science at these facilities. In this project, I propose a novel approach to overcome this bottleneck by exploiting a correlation and covariance analysis of the experimental data. Moreover, the envisaged approach will be used for the first demonstration of coherent control of molecular dynamics in the extreme ultraviolet spectral range.
