XL Semanal highlights the career of Carlos Hernández García

XL Semanal highlights the career of Carlos Hernández García
The magazine XL Semanal highlights the work and outstanding research career of Carlos Hernández García, a member of our research group at the University of Salamanca. In a recent article, the impact of his research in the field of attophysics—a discipline that allows the study of the smallest and fastest phenomena in the subatomic universe—is emphasized.
 

Hernández García, who has been awarded by the BBVA Foundation and the Spanish Royal Society of Physics, leads research that has enabled the generation of ultrafast laser pulses capable of freezing the movement of subatomic particles, such as electrons. This revolutionary technology opens new avenues for studying and controlling matter at the quantum level.

The article highlights not only his ability to unravel the mysteries of quantum physics but also the enormous potential his work holds for future applications in fields as diverse as electronics, energy, and medicine.

You can read the full article on the XL Semanal website and download it from this link.

From our research group, we celebrate the national recognition of these achievements and congratulate Carlos Hernández García for the acknowledgment of his dedication and efforts.

Visit of Researcher ZhenSheng Tao to the Laser Applications and Photonics Group

Visit of Researcher ZhenSheng Tao to the Laser Applications and Photonics Group

From July 19 to 24, the Laser Applications and Photonics Group hosted the visit of Dr. ZhenSheng Tao, a researcher from the State Key Laboratory of Surface Physics and the Key Laboratory of Micro and Nano Photonic Structures (MOE) at Fudan University in Shanghai (P.R. China). The visit provided an excellent opportunity for academic exchange and strengthening collaborations in the field of advanced photonics.

During the visit, Dr. Tao delivered a lecture titled “Solid-state High-order Sideband Spectroscopy and Microscopy”, where he presented his latest research on the ultrafast manipulation of electronic states in quantum materials. This field is crucial for quantum state engineering and ultrafast optical modulation. In his talk, he highlighted how strong-field driven materials can exhibit fascinating properties, such as the modification of topological states, modulation of optical properties, and band structure engineering.

Despite the potential of these properties, experimental techniques to study strong-field dressed quantum states are limited. In response to this challenge, Dr. Tao introduced high-order sideband spectroscopy and microscopy techniques, developed by his team, which enable energy-, time-, and space-resolved measurements of these quantum states. Among the key achievements, he presented the first measurement of the dephasing rates of strong-field dressed exciton states, identifying exciton dissociation as the primary dephasing mechanism. Furthermore, his team achieved the first 3D tomographic imaging of a mid-infrared anapole resonant field in a micrometer-thick silicon resonator.

These advancements highlight the potential of high-order sideband spectroscopy and microscopy as powerful tools for studying the ultrafast manipulation of quantum materials.

The lecture sparked a fruitful exchange of ideas with members of the group, who discussed potential applications and future collaborations in related areas, such as the characterization of materials at the nanoscale using advanced laser techniques. The visit also included a tour of the experimental facilities of the Laser Applications and Photonics Group, where Dr. Tao was able to observe the techniques developed by the local team. This allowed for a valuable technical exchange that laid the foundation for potential collaborative projects in the future.

In summary, Dr. ZhenSheng Tao’s visit was highly enriching, providing new perspectives on solid-state spectroscopy and laying the groundwork for future collaborations. Dr. Tao’s expertise and innovative approach were a great source of inspiration for the group, opening new horizons in the study of photonics and quantum science.

Visit and Collaboration of Ming-Chang Chen with the ALF Group at the University of Salamanca

Visit and Collaboration of Ming-Chang Chen with the ALF Group at the University of Salamanca
We are delighted to announce that Ming-Chang Chen from the National Tsing Hua University in Hsinchu, Taiwan, visited the Laser Applications Group at the University of Salamanca (USAL) from July 8th to July 10th, 2024. During his visit, in addition to holding meetings with the group’s researchers and touring the laboratory, he delivered a lecture on July 10th titled “Advancements in Turn-Key Attosecond Light Sources and Their Application in Probing Spin Dynamics.”
 

The collaboration between Ming-Chang Chen and the ALF group has a long history, dating back to 2016. As a result of this collaboration, several research articles have been published, thereby strengthening the bond between both institutions and significantly advancing the field of laser technology.

Prof. Chen established the ATTO-EUV lab in 2013 with the goal of generating bright and coherent EUV lasers on a tabletop. His recent research is dedicated to advancing laser technology and producing the shortest and brightest high-order harmonic EUV source. Notably, he pioneered and demonstrated the complete solution for controlling the polarization of isolated attosecond pulses and invented the broadband EUV polarimeter. By introducing the highly efficient post-compression technique, CASCADE, he enabled the production of single-cycle IR pulses and isolated attosecond EUV pulses. This accessible and reliable tabletop EUV light source has opened up numerous possibilities, including pioneering EUV spectroscopic ellipsometry and achieving the brightest EUV light source for nano-imaging.
