This interest is driven by the ethical dilemma surrounding the culling of non-productive day-old male chicks in layer-hen production and by the need to improve hatchery efficiency. Optical techniques are widely investigated for these applications\, but are challenged by the complex optical properties and heterogeneous structure of avian eggs. Here\, we show that chicken eggs display unusual photon trapping behavior due to the eggshell behaving like an integrating sphere\, considerably extending photon time-of-flight. Time-domain diffuse optical spectroscopy (TD-DOS) on egg phantoms\, supported by Monte Carlo simulations and post-dispersive filtering experiments\, rule out fluorescence as the source for the long photon time-of-flight. These results point to diffuse reflections at the inner surface of the eggshell as the source of the long photon time-of-flight. Despite these boundary effects\, the retrieval of internal bulk optical properties remains feasible via inversion of the diffusion approximation after selection of appropriate boundary conditions\, as was demonstrated in incubated eggs. Finally\, phantom experiments illustrate how the integrating sphere affects the temporal response of time-resolved Raman and fluorescence measurements\, highlighting critical challenges in non-invasive optical characterization of avian embryos.

The experiments demonstrating photonuclear production of radioisotopes have been carried out at the Scottish Centre for the Application of Plasma-based accelerators (SCAPA). 10 kBq of 67Cu was produced by irradiating enriched 68Zn over a five-hour irradiation period at approximately 1 Hz repetition rate\, which provides an important experimental benchmark. This work assesses the performance of current LWFA systems and establishes the requirements of future commercial LWFA-based systems and extrapolations suggests that the next stage of development. A facility based on optically pumped CO2 laser technologies could potentially achieve clinically relevant activity levels of 67Cu. The project is part of the MedRadLaser collaboration between the University of Strathclyde\, National Physical Laboratory\, the University of the West of Scotland\, and the UK Atomic Energy Authority. The studies will be extended and form part of the newly funded EUPOPA project. \nThe MedRadLaser collaboration involves Giuseppe Lorusso[1]\, Dino A. Jaroszynski[2]\, David O’Donnell[3]\, S.

They now enable powerful techniques such as dual-comb interferometry. These motion-free interferometers use two combs with slightly different line spacings to achieve exceptional accuracy\, speed and resolution. They enable compact integrated photonic devices and advanced applications in spectroscopy\, sensing and imaging. \n \n \n \n \n \n \n \n \n \n \n \n \n \n Watch the LLE Talk URL:https://lasers4.eu/event/laserlab-europe-talk-frequency-comb-interferometry/ CATEGORIES:Webinars ATTACH;FMTTYPE=image/png:https://lasers4.eu/wp-content/uploads/Thumbnail_picque.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Berlin:20260924T143000 DTEND;TZID=Europe/Berlin:20260924T163000 DTSTAMP:20260701T084803Z CREATED:20260701T071312Z LAST-MODIFIED:20260701T084803Z UID:7766-1790260200-1790267400@lasers4.eu SUMMARY:Lasers4EU Webinar: The use and impact of artificial intelligence in research and innovation\, 24 Sept 2026 DESCRIPTION:This webinar will look at how AI is becoming an integral part of the research process\, from accelerating discovery through intelligent data analysis to supporting researchers as a ‘scientific co-pilot’ in design and decision-making.
