Speaker: Jonas B. Ohland (GSI Helmholtz Center for Heavy Ion Research) The Apollon Real-Time Adaptive Optics (ARTAO) system addresses air turbulence-induced Strehl ratio fluctuations in Apollon, the 10 PW Ti:Sapphire laser system in France. With a 50 m multi-pass amplifier and a 140 mm beam diameter, turbulence previously caused significant beam quality instability. To resolve […]
Speaker: Panagiotis A. Loukakos (IESL-FORTH) In this talk I will present our recent work on the application of laser-surface processing in the fabrication of nanostructured metallic electrodes. These electrodes have been found to exhibit enhanced electrochemical properties and they have been used in water-splitting electrochemical cells where we have found that they produce almost 5 […]
Speaker: Chiara Caldini (LENS) Cellular compartmentalization is the separation of the cellular interior into distinct compartments, each with specific conditions and materials, that enable the simultaneous execution of different metabolic processes. This organization is essential for regulating cellular functions, as it enhances efficiency by minimizing the loss of intermediate products. While the compartmentalization of eukaryotic cells […]
Speaker: Irina Alexandra Paun (INFLPR) The biomedical engineering sector is one of the most rapidly growing industrial areas, bringing together engineering, medicine and biology, to develop novel technologies for medical treatment. Modern biomedical engineering advanced the concept of “reverse engineering”, which means building micro- and nano-structures with functional biomimicry by extracting design parameters from biological […]
Speaker: Mika Pettersson (Laserlab-NSC) Graphene and other 2D materials have many excellent properties but seldom they can be used as such in advanced applications. One option is to chemically modify and functionalize 2D materials. However, many applications require spatially selective functionalization and patterning. Laser-based methods offer many advantages in this regard. A common optical material […]
Speaker: Inka Manek-Hönninger (University of Bordeaux, CNRS-CELIA) Registration belowFemtosecond laser materials processing in the GHz-burst mode has attracted much attention in the last few years , especially for top-down percussion drilling in dielectrics thanks to the outstanding machining quality of the holes . In this contribution, I will first give an introduction to femtosecond laser […]
Speaker: Séverine Boyer (MINES-Paris/PSL) Orbital debris removal in low Earth orbit (LEO) opens the way to a new paradigm in space propulsion. The use of high-power pulsed laser interaction (HP PLI) offers a perspective in this field. This concept is based on laser ablation. The high-power HiLASE beamline facility (Dolní Břežany, Czech Republic), with Perla-B […]
Speaker: Jakub Cikhardt (Czech Technical University)The interaction of a focused high-power laser with matter results in the generation of an electromagnetic pulse (EMP). In the case of terawatt and petawatt lasers, the intensity of the EMP is strong enough to interfere with diagnostic signals and may cause malfunction or distortion of electronic devices. Moreover, the […]
Speaker: Christian Tzschaschel (University of Zurich) Weyl semimetals have emerged as a promising quantum material system to discover novel electrical and optical phenomena, due to their combination of nontrivial quantum geometry and strong symmetry breaking. Here, I will present the observation of the nonlinear optical diode effect (NODE) in the magnetic Weyl semimetal CeAlSi, where […]
Speakers: Eleanna Pirgianaki (IESL-FORTH) In recent years, photoacoustic (PA) techniques have gained significant role in the field of cultural heritage (CH) diagnostics, proving to be powerful tools for the detailed investigation of complex and fragile objects such as paintings, documents and murals. These techniques are based on the PA effect, which involves the generation of […]
Speaker: Andrzej Bartnik (MUT-IOE) Many experiments relevant to various processes in Space were devoted to support interpretation of astronomic observations. The experiments concern formation of astrophysical jets, photoionized plasmas in accretion disks around compact stars, supernovae explosions, matter formed inside giant planets, formation of interstellar dust, molecular processes in interstellar ices, formation of tholins etc. […]
Speaker: Maria Kandyla (National Hellenic Research Foundation) The need for advanced materials and systems with new functionalities has motivated the development of micro/nanostructures on solid surfaces, which are necessary for the fabrication of functional devices for novel applications. In this talk, we will discuss the development of functional micro/nanostructures, based on laser-processed surfaces. Coating micro/nanostructures […]
