Laser Physics and Fusion Research PhD Scholarships 2025 (Fully Funded)

The Deutsches Elektronen-Synchrotron (DESY) in Hamburg, Germany, is offering two fully funded PhD positions in laser development for the Inertial Confinement Fusion (ICF) program. These positions are part of the IGNYTe Project, a pioneering initiative under Germany’s Fusion 2040 strategy funded by the Ministry of Research, Technology and Space. The goal of this program is to accelerate advancements in laser-based fusion energy systems and contribute to global clean energy solutions.

This research project focuses on solving one of the major technical challenges in fusion: the generation of efficient ultraviolet (UV) laser light for direct-drive fusion target compression. Successful candidates will work on the development of advanced fibre-based and solid-state laser systems, nonlinear optics for UV light generation, and the integration of new laser technologies into DESY’s high-performance infrastructure.

By joining DESY, you will become part of an international research environment renowned for scientific excellence and innovation. The positions start on September 1, 2025, and allow you to contribute to impactful research while receiving a competitive salary and benefits.
