Schaberle (CLL\, Portugal) \n \n Watch the Talk\n \n \n \n \n \n Photoacoustic tomography (PAT) is based on the absorption of light by endogenous or exogenous molecules – organic or inorganic – and the subsequent generation of acoustic waves resulting of the rapid deposition of heat upon deactivation of the excited electronic states of these molecules. In practice\, PAT is used to imaging small animals\, e.g. mice\, using pulsed laser light with wavelengths capable of penetrating biological tissues (680nm-2300nm) and activating specific chromophores. The great advantages of PAT are the molecular contrast provided by the selective absorption of light and the resolution (microns) obtained by the high frequencies of acoustic waves.

Thanks to the collimated output beam\, RGB laser radiation can be efficiently launched in optical fibers which open new application prospects\, including uniform three laser line illumination for highly sensitive spectral imaging to improve performance of clinical diagnostics in dermatology and endoscopy. \nThis talk provides insight into the principles and methodology of triple spectral line imaging under RGB laser-fiber illumination\, and its implementation in lab-made prototype devices. For assessment of skin malformations\, two RGB laser based prototypes were developed – one for examination of relatively small skin areas (~2-3 cm in diameter) and one for spectral line imaging of larger skin areas of typical dimensions ~40-80 cm\, suitable also for full-body skin diagnostic imaging. The obtained three spectral line images are further transformed into distribution maps of three main skin chromophores to help clinicians in diagnosing the malformations with higher precision and reliability. For assessment of mucosa pathologies\, a triple RGB laser line illumination system to replace the traditional white light endoscopic illumination has been developed. Some clinical examples will be discussed\, as well; clinical tests of the developed devices are underways.

Potential applications of such reaction range from controlled nuclear fusion to radiobiology and cancer therapy. A laser-driven fusion approach consists in the interaction of high-power\, high-intensity pulses with H- and B-rich targets. We report on a pioneering experiment exploiting proton-boron fusion in CH/BN targets to obtain high-energy alpha particle beams (up to 5 MeV) using a compact approach and a tabletop laser system with a peak power of ~10 GW\, which can operate at high-repetition rate (up to 1 kHz). The secondary resonance in the cross section of proton-boron fusion (~150 keV in the center-of-mass frame) is exploited for the first time using a laser-based approach. The generated alpha particles are characterized in terms of energy\, flux\, and angular distribution using solid-state nuclear-track detectors\, demonstrating a flux of ~105 particles per second at 10 Hz\, and ~106 per second at 1 kHz. Numerical hydrodynamic and particle-in-cell simulations support our experimental findings. Potential impact of our approach on future spread of ultra-compact\, multi-MeV alpha particle sources driven by moderate intensity (1016-1017 W/cm2) laser pulses is anticipated.     URL:https://laserlab-europe.eu/event/laserlab-europe-talk-a-multi-mev-alpha-particle-source-via-proton-boron-fusion-driven-by-a-10-gw-tabletop-laser/ LOCATION:Online CATEGORIES:laserlab-europe events,laserlab-europe talk ATTACH;FMTTYPE=image/png:https://laserlab-europe.eu/wp-content/uploads/2024/11/lle-talk_2023-06_istokskaia_proton-boron.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20230426T160000 DTEND;TZID=Europe/Berlin:20230426T170000 DTSTAMP:20260416T232552 CREATED:20250130T104556Z LAST-MODIFIED:20250402T074936Z UID:10000080-1682524800-1682528400@laserlab-europe.eu SUMMARY:Laserlab-Europe Talk: Towards the detection of vacuum birefringence DESCRIPTION:Speaker: Gerhard Paulus (Helmholtz Institute Jena\, Germany) \n \n Watch the Talk\n \n \n \n \n \n Strong electromagnetic fields polarize vacuum such that it becomes birefringent. Not surprisingly\, the effect is tiny\, even if petawatt-class lasers are used for inducing the effect and X-ray lasers for probing it. Quite obviously\, the performance of the required X-ray polarimeters is the decisive bottleneck: an extinction ratio of 1011 or better is required. Gerhard Paulus and his team have been working since more than 10 years to remove the bottleneck. He will report how close they have come to the feasibility of a promising demonstration of vacuum birefringence. He will also explain how to design a reasonable experiment and which mistakes to avoid.   URL:https://laserlab-europe.eu/event/laserlab-europe-talk-towards-the-detection-of-vacuum-birefringence/ LOCATION:Online CATEGORIES:laserlab-europe events,laserlab-europe talk ATTACH;FMTTYPE=image/jpeg:https://laserlab-europe.eu/wp-content/uploads/2024/11/lle-talk_2023-04_paulus_vacuum-birefringence.jpg END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20230329T160000 DTEND;TZID=Europe/Berlin:20230329T170000 DTSTAMP:20260416T232552 CREATED:20250130T104901Z LAST-MODIFIED:20250402T074929Z UID:10000081-1680105600-1680109200@laserlab-europe.eu SUMMARY:Laserlab-Europe Talk: Complex molecules in stellar nurseries DESCRIPTION:Speaker: Sandra Bruenken (FELIX Laboratory\, Netherlands) \n \n Watch the Talk\n \n \n \n \n \n Complex organic molecules\, including polycyclic aromatic hydrocarbons (PAHs)\, are found in a large variety of astronomical environments\, including low temperature and low density molecular clouds in the interstellar medium which are the birthplaces of new stars and planets. Laboratory astrophysical studies on chemical reaction pathways under astronomically relevant conditions are crucial to interpret astronomical observations and as input for simulations in astrochemical networks. Of similar importance are spectroscopic studies of the often elusive\, but essential\, molecular reaction partners\, intermediates and products that yield fundamental insights on their structure\, and provide spectroscopic signatures needed for their identification in space. \nCryogenic ion traps have proven to be ideal tools for studying ion-molecule reactions under controlled conditions and enable sensitive spectroscopic studies of mass-selected\, cold\, and isolated molecular ions. Here\, Sandra Bruenken will describe the combination of such a cryogenic 22-pole ion trap instrument with the widely tunable infrared free electron lasers at the FELIX Laboratory [1]. Infrared action-spectroscopy is used to structurally characterize isomeric ions formed upon (dissociative) ionization of neutral species\, allowing us to unravel their fragmentation processes (top-down processes). Very recently\, they developed a novel combination of ion-molecule reactivity studies and infrared spectroscopy to elucidate and disentangle formation routes of complex molecules (bottom-up processes) at astronomically relevant temperatures\, and have in this way identified an efficient low-temperature PAH-growth pathway from mono- to polycyclic aromatic hydrocarbons [2]. \nReferences \n[1] P.

In these conditions\, collective plasma effects driven by relativistic flows\, ultra-high field intensities\, and quantum electrodynamics effects are intertwined. In many scenarios\, these relativistic and quantum effects can have direct consequences on the collective plasma dynamics. \nThe underlying first principle mechanisms are highly nonlinear\, and occur at scales far from the plasma or the object scales\, making these processes intrinsically multi-scale\, and thus requiring a combination of theory and large-scale numerical simulations for a detailed analysis. The conditions under which extreme plasma physics can be relevant will be discussed\, along with the recent progress (from large-scale simulations of compact objects to multi-dimensional ultra-intense laser-plasma interactions)\, illustrating how ultra-intense electromagnetic fields approaching the critical Schwinger field impact the collective plasma dynamics. This interplay will be emphasized\, and the main challenges and open questions will be presented. \nWork partially supported by the European Research Council (AdG InPairs).

In the recent years\, this spectroscopic method has proven its capabilities in molecular spectroscopy in different spectral regions ranging from the visible across the infrared spectral region into the THz domain [1-3]. The UV has so far been neglected for fingerprinting although electron transitions are as element specific as rovibrational transitions and the corresponding absorption cross sections can be huge (> 100 Mb). Especially molecular gasses of astrophysical and environmental relevance have strong and congested absorption characteristics in this spectral region (few examples: NO2\, CO\, SO2\, HCHO). Birgitta Schultze-Bernhardt will present their latest efforts on expanding dual comb spectroscopy via non-linear frequency up-conversion into the ultraviolet region. The challenges include UV frequency comb generation with a high photon flux\, efficient UV interferometry and fast UV signal detection [4]. \nBirgitta Schultze-Bernhardt is a university professor at the Institute of Experimental Physics at TU Graz\, Austria. Schultze-Bernhardt`s research focus involves the development of ultraviolet frequency comb generation for high resolution molecular spectroscopy. \nReferences \nB. Bernhardt\, A. Ozawa\, P.

Their extent can be tremendous during the interaction of the high intensity laser peak (I~1016 W cm-2) with the precompressed corona and they are expected to scatter a significant amount of laser energy and to generate large fluxes of suprathermal electrons (HE)\, with a considerable impact on both the shock pressure and the preheat of the fuel capsule. The non-linear character of these instabilities becomes progressively more important with the increase of laser intensity\, which makes the extrapolation of analytical models quite inaccurate; a more detailed understanding of these processes therefore calls for experiments dedicated at investigating Laser Plasma Interaction (LPI) in conditions as close as possible to those envisaged in SI. \nIn this presentation\, we report results obtained in experiments at Gekko XII\, PALS and VULCAN laser facilities\, focussed at investigating LPI and at identifying the mechanisms originating suprathermal hot electrons. In all of them\, Stimulated Raman Scattering and Two Plasmon Decay were accurately and time-resolved characterized by means of spectroscopic and calorimetric tools\, while a full set of diagnostics – including Ka imaging and spectroscopy\, Bremsstrahlung cannons and Magnetic Electron Spectrometers – were used for achieving an energy-resolved characterization of hot electrons. The regime of interaction in these experiments is significantly different\, with laser intensity ranging from Il2 ~2·1014 Wmm2/cm2 to ~2·1016 Wmm2/cm2\, plasma density scalelength rising from 50 to 400 mm\, laser wavelength going from the UV to the IR range\, laser irradiation in single- and multi-beam configuration\, allowing a good understanding of the role played by the different experimental parameters. \nAfter critically discussing the experimental results\, we will show here the future directions of our research in this field and the aims of the forthcoming experiments.

Analysis of scattering data is a very time-consuming process as it requires solving an ill-posed inverse problem to infer properties of the imaged object. \nWe will be discussing two state-of-the-art methods to solve this task: 1) ML-based estimation of the most important parameters of the object in a single step given the experimentally acquired scattering image; 2) Iterative ML-assisted phasing based on automatic differentiation that can be very easily used for fast reconstruction of multiple X-ray scattering modalities such as CDI\, mono- & polychromatic Ptychography as well as Holography. \nSome parameters exhibit low contribution to the acquired data which also hampers reliable predictions and discrimination of these parameters. We show that normalising flows can be used to recover the predictive posterior distribution of these parameters to resolve ambiguous situations and provide information about the reliability of the estimate.

Most of us are aware of the fact that light can be thought of consisting of photons. It is less well known that atoms can behave just like (matter)waves\, which can be manipulated in a manner analogous to light: We now can create matterwave lenses\, waveguides\, interferometers and even matterwave amplifiers and lasers. \nIn this colloquium\, I will introduce the basics of matterwave (optics) as well as some of its applications to precision sensing. I will also present some of the research results of the Cretan Matterwaves Group\, where we have demonstrated a CERN-like matter-wave accelerator and fully-coherent matterwave guide [1] as well as matterwave-lensing down to the pico-kelvin regime. \nReferences \n[1] Saurabh Pandey et al.

A sequence of coincidences\, bright postdocoral fellows and an overworked intensive care physician with an amazing insight into the needs came together for us to embark in an international\, multi-center clinical trial with minimal funding. This then led to a Horizon 2020 project partially enabled by our longstanding collaborations in LaserLab JRAs. In the talk i will describe the technologies\, their fundamental physical background\, how we are using them and what we believe their future impact would be.

The National Ignition Campaign\, though a marvel in term of laser technology and data quality in this challenging regime\, has failed to achieve ignition. This failure has shed lights on gaps of our understanding of fundamental plasma properties such as thermal transport or emissivity. Following these initial difficulties\, evolution of the design (higher adiabat\, new ablator\, new hohlraum conditions) has led to significant improvement in implosion performance over the years and finally to performance close to ignition (Q=0.7) in the summer of 2021. The talk will go over these evolutions and why they led to the recent successes obtained on the NIF. \nThe talk is organised within the framework of the Laserlab-Europe Expert Group on Laser-driven Inertial Confinement Fusion (ICF) – Inertial Fusion Energy (IFE).

Recent developments of this ultrafast laser technique supported with the advances in material sciences allows 3D printing of inorganic structures routinely via combination of maskless photopolymerization and thermal post-treatment (pyrolysis or calcination). \nThe current achievements are very promising for technical applications where highly resilient structures (made out inertial materials for extended durability) are required\, such as harsh environments\, high intensity optics\, and open space. In this talk the physical and chemical principles for 3D nano-structuring of inorganics employing laser lithography\, hybrid and composite materials as well as post-treatment are covered. The most recent advances are overviewed and the major achievements are highlighted\, among them are: sub-100 nm feature fabrication\, crystalline nanostructures\, resilient\, high refractive index and transparent materials. Advances and limitations within the context of the emerging trends and potential immediate applications are discussed in details.
