LaserFusion Concludes Specialized Pisa Course, Equipping Researchers with Advanced Diagnostic Skills

The LaserFusion Consortium successfully concluded its second specialized training event, a 5-day course on “Physics and Technology of Inertial Fusion Energy,” at the National Institute of Optics of the National Research Council (INO-CNR) in Pisa, Italy. The intensive program, which ran from November 3 to 7, 2025, provided 20 postgraduate students with deep, hands-on expertise in the critical field of plasma diagnostics.

Following the foundational Bordeaux school, the Pisa course marked a strategic shift to advanced, application-focused training. The curriculum was dedicated to the sophisticated diagnostic techniques required to probe the extreme states of matter in laser-driven fusion experiments, blending cutting-edge theory with indispensable practical skills.

A Curriculum Forged in Theory and Practice

The course offered a balanced and immersive experience:

  • Expert-Led Theory: Participants engaged with a comprehensive lecture series delivered by INO-CNR’s leading scientists, covering laser-plasma interaction, proton probing via TNSA, X-ray diagnostics, parametric instabilities, laser diagnostics, and interferometry.

  • Consortium Insights: The theoretical foundation was broadened by seven specialized seminars from researchers across the LaserFusion partner network, highlighting diverse European perspectives and ongoing research frontiers.

  • Hands-On Laboratory Core: The defining element of the week was the direct, practical training in key experimental techniques. Under expert guidance, the 16 MSc and PhD students conducted hands-on sessions in:

    1. Wavefront reconstruction of a He-Ne laser and phase plate analysis.

    2. Precision alignment of Off-Axis Parabolic (OAP) mirrors.

    3. Investigating wavefront changes induced by mechanical stress on mounted optics.

The selected participants, representing the consortium’s eight partner institutions, formed a dynamic and collaborative group. Their active involvement in labs and seminars fostered not only individual learning but also strengthened the professional network essential for future collaborative research in European fusion science.

The successful completion of the Pisa Diagnostic Course represents another concrete step in LaserFusion’s mission. By sequentially building from broad principles to specialized skills, the consortium is creating a structured pathway for developing expert researchers.
