  • Laserlab-Europe Talk: Extreme plasma physics with lasers and in astro

    Online

    Speaker: Luis Silva (IST, Portugal) Many extreme astrophysical scenarios share common underlying microphysics with laboratory scenarios with relativistic particle beams and ultra-intense lasers. 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 […]

  • Laserlab-Europe Talk: Complex molecules in stellar nurseries

    Online

    Speaker: Sandra Bruenken (FELIX Laboratory, Netherlands) 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 […]

  • Laserlab-Europe Talk: Towards the detection of vacuum birefringence

    Online

    Speaker: Gerhard Paulus (Helmholtz Institute Jena, Germany) 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 […]

  • Laserlab-Europe Talk: A multi-MeV Alpha Particle Source via Proton-Boron fusion driven by a 10-GW Tabletop Laser

    Online

    Speaker: Valeria Istokskaia (ELI Beamlines, Czech Republic) Nuclear fusion between protons and boron-11 nuclei has undergone a revival of interest thanks to the rapid progress in pulsed laser technology. 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 […]

  • Laserlab-Europe Talk: RGB lasers in dermatology and endoscopy

    Online

    Speaker: Janis Spigulis (University of Latvia)RGB lasers that emit simultaneously three spectral lines (red, green and blue) are gaining increased applications, mainly related to color projections and color TV. 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 […]

  • Laserlab-Europe Talk: Time-resolving energy dissipation pathways in materials

    Online

    Speaker: Jens Biegert (ICFO, Spain) A standing challenge in material and molecular sciences is identifying how excitation dissipates. Jens Biegert will show that attosecond soft x-ray spectroscopy provides a powerful new analytical tool for an engineered approach to remedies. After describing the attosecond methodology, he will discuss recent graphite results, a material that is relevant […]

  • Laserlab-Europe Talk: Scientific fundamentals and practice of Photoacoustic Tomography

    Speaker: Fábio A. Schaberle (CLL, Portugal) 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 […]

  • Laserlab-Europe Talk: Multimodal and Multiscalar Hyperspectral Imaging

    Online

    Speaker: Alessia Candeo (POLIMI, Italy) Hyperspectral imaging (HSI) is a powerful technique that couples optical imaging with spectroscopy, allowing for the acquisition of spatially resolved spectral data from a sample. Typically, HSI systems rely on spectral or spatial filters, which can constrain the acquisition throughput. We propose an innovative approach based on Fourier Transform, in […]

  • Laserlab-Europe Talk: Multi-pass cells – quasi-guiding systems for laser pulse post-compression and advanced nonlinear optics

    Online

    Speaker: Christoph Heyl (DESY, Germany) Nonlinear multi-pass cells (MPCs) have brought exciting opportunities to the field of ultrafast optics, ranging from major advances in post-compressed ultrafast lasers to novel frequency conversion schemes. As a hybrid concept bridging free-space and guided-wave nonlinear optics, MPCs overcome several limitations of traditional nonlinear optics approaches. Here, I discuss the […]

  • Laserlab-Europe Talk: Towards sustainability by applications of laser processing

    Online

    Speaker: Juraj Sládek (HiLASE, Czech Republic) Laser material processing, aside from cutting and welding applications, is also applicable for advanced surface modification of a broad range of materials. This includes surface functionalization to achieve superhydrophobic, self-cleaning or passive antibacterial surfaces, reduced friction and wear of metallic components, increased surface area for battery electrodes and more. […]

  • Laserlab-Europe Talk: Some representative results on planetology of laboratory at LULI

    Online

    Speaker: Alessandra Benuzzi-Mounaix (CNRS-LULI, France) While the number of exoplanets detected is growing at such an incredible pace as to make them a new class of astrophysical objects, the physical properties required for modelling their interiors are currently lacking. In addition to exoplanet modelling, important controversies also remain for the planets constituting our solar system. […]

  • Laserlab-Europe Talk: Lasers, related radiation sources and diagnostics at ENEA-Frascati for applications to material science, radiation hardness of materials and components

    Online

    Speaker: Fabrizio Consoli (ENEA, Italy) The ENEA-Centro Ricerche Frascati has a very long-standing tradition on lasers and applications. The first laser operated here in the ‘60s, just after the first Maiman’s experiment . The activity has embraced over the years different laser approaches and regimes. In the frame of high energy and high intensity lasers, […]
