The new research project, SpecX (Schemes for the generation of attosecond x-ray special beams using high-order harmonic generation from macroscopic targets), has started, with Julio San Román and Carlos Hernández Garcia as the principal investigators. In the SpecX project, they aim to advance in the macroscopic management of ultrarapid light beams, from the femtosecond/infrared to the attosecond/X-ray regime, with special emphasis on the study of complex topological fields. To do this, advanced simulation codes are required, given that the mechanisms for generating such short laser pulses, through nonlinear laser post-compression or high-order harmonics generation, combine microscopic and macroscopic physics, which poses a great challenge.
To achieve this goal, the following objectives have been defined:
- Exploit high-performance computational strategies that use artificial intelligence to access these new extreme non-linear optical scenarios.
- Design ultrarapid pulses structured in the femtosecond/infrared regime through different non-linear propagation schemes, such as the use of hollow core fibers and photonic crystals, and multipass cells.
- Explore new schemes for the process of high-order harmonics generation in the X-ray and attosecond regime, such as crystalline solids irradiated by fields.
- Explore the generation of high-order harmonics with post-compressed laser pulses in combined regimes.
- Propose new experimental proposals for the generation of structured X-ray fields in the attosecond regime.
The SpecX project falls under the Call Programa Estatal para Impulsar la Investigación Científico-Técnica y su Transferencia, del Plan Estatal de Investigación Científica, Técnica y de Innovación 2021-2023. It has a duration of three years and has received funding of €127,500 from the Ministerio de Ciencia e Innovación and Agencia Estatal de Investigación, co-financed by the European Regional Development Fund (ERDF).
