El próximo 17 de octubre, nuestro compañero Luis Plaja impartirá la charla «A F***ing attosecond!: Celebrando el Nobel de Física 2023» dentro del programa +Física. Tendrá lugar a 13:00 en el aula III del Edificio Trilingüe en la Universidad de Salamanca.
Next-generation nano and quantum devices have increasingly complex 3D structure. As their dimensions shrink, their performance is often governed by interface quality or precise chemical, interfacial or dopant composition. However, correlating their structural and functional properties is challenging.
High harmonic quantum light sources provide an exquisite source of short wavelength light, with unprecedented control over the spectral, temporal, polarization and orbital angular momentum (OAM) of the emitted waveforms, from the UV to the keV photon energy region. These advances are providing powerful new tools for near-perfect x-ray functional imaging, and for engineering the illumination to achieve high-fidelity imaging – akin to the vortex beams used in visible super-resolution imaging.

El próximo 25 de abril, nuestro compañero Iñigo Sola dará la charla «Espectroscopía de bolsillo» dentro del programa +Física. Tendrá lugar a 13:00 en el aula III del Edificio Trilingüe en la Universidad de Salamanca.
El 2 de febrero, Carlos Hernández García, investigador Ramón y Cajal, miembro del grupo de investigación Aplicaciones Laser y Fotónica e investigador principal del proyecto Attostructura (ERC 851201) impartió el seminario «Structuring ultrafast laser light through highly nonlinear physics» dentro del ciclo de seminarios del Instituto Rocasolano del 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

El pasado 12 de noviembre, Kevin Dorney, investigador postdoctoral y miembro MSCA del laboratorio AttoLab del imec (Interuniversity Microelectronics Centre) en Leuven (Belgium) visitó el grupo de Aplicaciones Laser y Fotónica como parte de las actividades previstas en el proyecto ERC Attostructura.
Kevin Dorney nos ofreció el seminario titulado «Imec’s AttoLab: Bridging the Gap Between Fundamental Ultrafast EUV Science and Practical Metrologies for the Semiconductor Industry» en el que habló del laboratorio que han construido en las instalaciones del imec, la infraestructura que lo forma y las técnicas y capacidades de las que disponen.
