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. […]
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, […]
Speaker: Teresa Cebriano Ramírez (CLPU, Spain) The CLPU operates VEGA, a multi Terawatt laser system composed by three independent and synchronized 30 fs long pulses: VEGA-3 of 1 PW (at 1Hz), VEGA- 2 of 200 TW and VEGA-1 of 20 TW (both up to 10 Hz). The interaction of these pulses with matter (in solid, […]
Speaker: Nirit Dudovich (Weizmann Institute of Science, Israel) High harmonic generation (HHG) spectroscopy has been successfully applied over the past two decades to resolve fundamental strong-field phenomena in atoms, molecules and solids. An important aspect of HHG spectroscopy lies in its coherent nature. The strong-field interaction directly transfers the coherence of the laser field into […]
Speaker: Adrien Mau (Abbelight, France) Microscopy is the art of observation of the infinitely small. However, one cannot observe an object without collecting light from it, and thus first sending light at it. We will present how laser illumination coupled to smart optomechanical devices improved the traditional sample illumination methods. Notably, our company Abbelight has […]
Speaker: Lisa Kobayashi (ICFO, Spain) Diffuse correlation spectroscopy (DCS) is an established diffuse optical method which non-invasively measures regional, microvascular blood flow from laser speckles. Although the utility of DCS has been demonstrated in clinical trials relating to a variety of clinical conditions, limited signal to noise have restricted the use of DCS to measure, […]
