A study of the formation of Laser Induced Periodic Surface Structures (LIPSS) using near-infrared femtosecond pulsed laser irradiation on poly(ethylene terephthalate) (PET) films deposited over gold substrates has been carried out. We report the influence of the gold substrate roughness and the PET film thickness on LIPSS formation and analyze it in terms of the
On the occasion of the proclamation of May 16 as “International Day of Light and Light-Based Technologies” by the United Nations Organization, the Master’s Degree in Laser Physics and Technology” announces the V edition of the Photo Contest “Day of the light”. In the organization of the contest and formation of the jury participate: the
The use of fracture mechanics for rationalizing the fracture behavior of cemented carbides is valid, as far as sharp cracks, free of residual stresses and subjected to a well-defined stress state are used for assessing fracture toughness. However, machining a very sharp notch on the surface of hardmetals for fracture toughness testing has been a
From September 12 to 16, the annual meeting of the European Optical Society (EOSAM 2022) was held in Porto (Portugal). The Laser and Photonics Applications group (ALF – USAL) has participated in this conference presenting some of the most recent results of the research it is currently carrying out. The works presented were: Marina Fernández
Nowadays, the high-order harmonic generation process is an extended useful tool for the study of femtosecond dynamics. Nevertheless, there are still many doubts regarding the electron behavior inside different types of mediums. Recent studies in solid targets have revealed new scenarios with extraordinary electronic dynamics compared with atoms or molecules. The process in solids can be
The television channel Castilla y León Television publishes on its website the news about the meeting of the expert council of the ATTOSTRUCTURA project. You can read the press release and watch the video on their website.
Next August will be thirty months since the ATTOSTRUCTURA project began, which means that half of its duration has already elapsed. For this reason, the first meeting of the project’s scientific advisory committee has been held. The committee, made up of external researchers who are experts in the different fields of the project, has the
From July 11 to 15, the XXXVIII Biennial Meeting of the Royal Spanish Society of Physics was held. The Laser and Photonics Applications group (ALF – USAL) has participated in said biennial, presenting some of the most recent results of the research it is currently carrying out. The works presented were: Luis Sánchez-Tejerina, Rodrigo Martín-Hernández,
The OSAL Student Chapter of the University of Salamanca has been awarded second place at the Foton 2022 Awards in the Foton Emitted category, for its informative video “The colors in soap bubbles”. The jury has positively valued “his ability to disclose to the general public, explaining the operation of the phenomenon of interference of
Sterling silver jewelry, rose gold with exclusive designs, rings, earrings, bracelets… made out of light? Like a high fashion jewelry workshop, the Laser and Photonics Applications research group of the University of Salamanca (ALF-USAL) focuses its efforts on designing light jewels through non-linear optics. Jewels, not only for their beauty in the form of high-frequency
