Generation and applications of attosecond structured light pulses

The development of structured ultrafast laser sources is a key ingredient to advance our knowledge about the fundamental dynamics of electronic and spin processes in matter. It is widely recognized the relevance of ultrafast sources structured in their spin angular momentum (associated to the polarization of light) and orbital angular momentum (associated with the transverse phase profile, or vorticity of a light beam) to study chiral systems and magnetic materials in their fundamental temporal and spatial scales. In the last decade, the possibility to generate structured ultrafast laser pulses in the shortest time scales known, as attosecond pulses, has triggered substantial developments in nonlinear optics. In this talk we will review several works that have boosted the field of attosecond structured pulses during the last decade. We will focus in the generation of EUV/soft x-ray pulses tailored in their spatiotemporal angular momentum properties and we will review their potential applications in fundamental and applied science. Finally we will review how artificial intelligence has boosted the theoretical advancements in attosecond pulse generation.
