Based on the current state of the art for XUV ultrashort sources carrying angular momenta, we identified the following objectives to be realistic within a 5 year period.
Orbital Angular Momentum
- Identify in the extreme non linear regime of HHG the conservation rules of OAM
- Test and report on the most suitable ways to measure the OAM of a femtosecond light beam carrying OAM
- Design XUV femtosecond light beam carrying arbitrary OAM
- Identify the role of phase matching during the upconversion of a visible beam through HHG
Spin Angular Momentum
- Study and report on different approaches to provide XUV femtosecond HHG based sources carrying SAM
- Provide the most complete measurement of polarization of HHG, including helicity
- Establish the time-resolved PECD technique (TR-PECD) as a diagnosis tool of chemical physics.
- Probe the chirality of excited states of chiral molecules.
- Contribute to the understanding of the mechanisms governing the conservation or loss of molecular chirality after an electronic excitation using pump-probe schemes at the femto and attosecond timescales.
