Stage I

• The ELIFOAM project initiated the fabrication and preliminary characterization of materials using Pulsed Laser Deposition (PLD), aiming to explore suitable morphologies for low-density free-standing targets dedicated to high-power laser experiments.
• Efforts focused on defining a reproducible PLD procedure capable of generating both compact films and foam-like porous architectures, in line with the project objectives regarding tunable morphology and material density.
• In parallel with experimental work, we also began the evaluation process for acquiring a Raman system capable of advanced 2D and 3D mapping. The Raman system is essential for monitoring structural isotropy and internal uniformity of future free-standing foams. Offers were collected from Horiba, Renishaw and SOL Instruments, and the technical documentation is currently being developed to ensure the purchase of an instrument that fully meets the ELIFOAM scientific needs and long-term target characterization strategy.
• Raman tests performed in the current phase confirmed that carbon foam structures provide clear, high-contrast spectral signals, further supporting the necessity and relevance of acquiring a mapping-capable Raman system for subsequent project stages.
• These preliminary results were disseminated in the frame of a scientific seminary (28.11.2025) where the ELIFOM team from INFLPR proposed new approaches to fulfil the next objectives of project.
