Speaker: Birgitta Schultze-Bernhardt (Graz University of Technology, Austria) Dual Comb Spectroscopy combines high spectral resolution with broad spectral coverage and short measurement times. 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 . The […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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. […]
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. […]
