PARTICIPATION OF RESEARCHERS FROM THE LASER AND PHOTONICS APPLICATIONS GROUP IN ICOAM2024

PARTICIPATION OF RESEARCHERS FROM THE LASER AND PHOTONICS APPLICATIONS GROUP IN ICOAM2024
Researchers Carlos Hernández García and Rodrigo Martín-Hernández, members of the Laser and Photonics Applications Group and the ERC Attostructura project (851201), actively participated in the Seventh International Conference on Optical Angular Momentum. This prestigious conference took place from June 10 to 13, 2024, at Kruger National Park, South Africa.
 

The Seventh International Conference on Optical Angular Momentum (ICOAM 2024) is a prominent event in the field of optics and photonics, focusing on the study and applications of light’s angular momentum. This event gathers scientists and experts from around the world to discuss the latest advancements and share innovative research in areas such as particle manipulation, quantum optics, generation of angular momentum beams, and biomedical and communication applications.

  • Carlos Hernández García participated as an invited speaker with his work titled “Attosecond vortex pulse trains”.

The landscape of ultrafast structured light pulses has recently evolved thanks to the capability of high-order harmonic generation (HHG) to nonlinearly convert orbital angular momentum (OAM) from infrared to extreme-ultraviolet/soft X-rays. Up to now, HHG has been demonstrated to produce harmonic vortex pulses on the femtosecond scale through various studies, where higher-order harmonics exhibit distinct OAM content. This characteristic, a result of OAM conservation rules, has hindered the emission of vortex beams with attosecond pulse durations.

In this work, we demonstrate, both theoretically and experimentally, the generation of attosecond vortex pulse trains – a succession of light pulses each with a temporal duration of hundreds of attoseconds, and a similar helical wavefront. This achievement is realized by synthesizing a comb of high-order harmonics with identical OAM. To our knowledge, these are the first vortex pulses produced on the attosecond scale.

To achieve this, we drove HHG with an infrared bifurcated polarization tilt-angle grating, resulting from the non-collinear superposition of two counter-rotating circularly polarized beams with opposite OAM. The simultaneous conservation of linear momentum, spin angular momentum, and orbital angular momentum in the HHG process leads to two spatially-separated circularly polarized high-order harmonic beams with OAM independent of the order. Our work paves the way towards attosecond-resolved light-matter interactions at the natural timescale of electronic dynamics in atoms, molecules, or solids.

  • Rodrigo Martín-Hernández participated in the poster session with the work titled “How to generate spatiotemporal optical vortices in the extreme-ultraviolet/x-ray regime.”

The generation of spatiotemporal optical vortices (STOVs) in the near-infrared regime has been successfully studied in recent years, both theoretically and experimentally. However, their extension to higher-frequency regimes has not yet been demonstrated. Over the last decade, it has been shown that high-order harmonic generation (HHG) can successfully transfer longitudinal optical vortices from the near-infrared to the extreme-ultraviolet (EUV) and X-ray regimes. Following an immediate analogy, one might think that HHG driven by STOVs would result in high-frequency STOVs with high topological charge. However, this scenario offers much richer possibilities.

In this work, we explore the nonlinear conversion of STOVs from the near-infrared to EUV/X-rays using HHG. Depending on the driving beam configuration, we identify two scenarios that lead to strongly differentiated phenomena.

Firstly, if HHG is driven by a canonical, elliptical, single-charged STOV focused on a gas target, high-frequency harmonic STOVs with the same topological charge as the driving field are generated. Our theoretical calculations unequivocally demonstrate that this result depends heavily on the non-perturbative nature of the HHG process. Thus, these results not only provide harmonic combs of low-topological charge STOVs in the EUV/X-ray range but also open the door to investigating some of the most fundamental questions about the intrinsic non-perturbative nature of the HHG process.

Secondly, if the driving beam is designed to deliver a canonical (elliptical), single-charged STOV at the gas target, high-order harmonic STOVs with high topological charge are generated. We demonstrate that in this scenario, the resulting topological charge of the harmonic STOVs increases according to the harmonic order multiplied by the fundamental topological charge, following the same well-known conversion rule as in longitudinal optical vortices.

Carlos Hernández García and Rodrigo Martín-Hernández’s participation in ICOAM 2024 underscores the Laser and Photonics Applications Group’s commitment to cutting-edge research and international collaboration in the field of optics and photonics. Their work not only contributes to the advancement of scientific knowledge but also opens new opportunities for innovative technological applications.

Innovadores supplement of El Mundo echoes the new research into ultraviolet structured light

Innovadores supplement of El Mundo echoes the new research into ultraviolet structured light

The newspaper El Mundo in its supplement Innovadores Castilla y León publishes a report on the new investigation being carried out by the ALF – USAL Group.

This research demonstrates the production of a type of laser beam in the extreme ultraviolet with a special design in phase and polarization.

In this type of beam, the polarization distribution is linked to the phase structure. These light forms are called vector vortices, because the structure is analogous to that of a whirlpool with different directions of vibration. It is, therefore, a light beam that combines the properties of the orbital angular momentum of light associated with the optical vortices with those of the spin angular momentum of the light particles, which defines the polarization.

The study from which the results presented in the publication have been obtained is the result of the collaboration between the ALF – USAL Group with the Paris-Saclay University and the Colorado School of Mines and is part of the European project ERC ATTOSTRUCTURA (851201)

Attostructura Seminar – Structuring ultrafast laser light through highly nonlinear physics

Attostructura Seminar – Structuring ultrafast laser light through highly nonlinear physics

On February 2nd, Carlos Hernández García, Ramón y Cajal researcher, member of the Laser and Photonic Applications research group and principal investigator of the Attostructura project (ERC 851201) gave the seminar “Structuring ultrafast laser light through highly nonlinear physics” within the cycle of seminars of the Rocasolano Institute of the CSIC.

The degree of control we have achieved over the manipulation of light is truly amazing. Initiated by our Greek ancestors using mirrors to guide light, we live in a world where the most advanced laser technology allows us to create and sculpt light beams with great precision. In particular, nowadays we can create ultrashort attosecond pulses (with durations of trillionths of a second), of very high frequencies (up to the soft X-rays), and with increasingly complex spatial structures thanks to our ability to harness their angular momentum. In this talk we will review our recent work in the generation of structured ultrashort laser pulses. Thanks to the highly nonlinear process of high harmonic generation, we can tailor the spin and orbital angular momentum properties of extreme ultraviolet/soft x-ray laser pulses directly at their generation. By properly controlling the process of high harmonic generation, from the driving laser beam to the target (gas or solid), different families of structured ultrashort laser beams can be created: self-torqued beams, vector-vortex beams, tunable high-frequency combs, or hexagonal harmonic beams. These new optical tools allow us to fantasize of new laser-matter interaction processes at the nanoscale, whose physical laws are yet to be discovered. For example, structured laser pulses offer an appealing alternative to study sub-femtosecond magnetization dynamics, where a complete understanding of the electronic and spin interactions remains unexplored

The University of Salamanca leads a pioneering international research project on ultraviolet structured light

Several media outlets have echoed the publication of a new research article by the ALF – USAL Group in the prestigious Optica magazine. It demonstrates the production of a type of laser beam in the extreme ultraviolet with a special design in phase and polarization.

In this type of beam, the polarization distribution is linked to the phase structure. These light forms are called vector vortices, because the structure is analogous to that of a whirlpool with different directions of vibration. It is, therefore, a light beam that combines the properties of the orbital angular momentum of light associated with the optical vortices with those of the spin angular momentum of the light particles, which defines the polarization.

The authors explain that “the fundamental idea is to control the properties of ultraviolet light by acting on the initial infrared light, thanks to the fact that all the information is encoded in the physical laws of conservation.” In fact, in this study a new conserved quantity is also discovered in the harmonic generation process, the Pancharatnam topological charge, which includes in its definition both the spin and the orbital angular momentum of the light beam.

The study from which the results presented in the publication have been obtained is the result of the collaboration between the ALF – USAL Group with the Paris-Saclay University and the Colorado School of Mines and is part of the European project ERC ATTOSTRUCTURA (851201)
