For our location in Hamburg we are seeking:
Postdoc - Lasers for Inertial Confinement Fusion
Remuneration Group 13 | Limited: 2 years | Starting date: 01.09.2025 | ID: FSPO007/2025 | Deadline: open | Full-time/Part-time
DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.
Over the recent years, DESY has also become an international hotspot for cutting-edge laser science. With the advent of inertial confinement fusion (ICF) research in Germany, DESY will boost its activities in this thriving research field.
We are seeking two motivated (one position can be filled with a candidate who just completed the PhD) and innovative Postdocs / Laser Scientists to join the IGNYTe project which is funded by the German Ministry of Research, Technology and Space in the scope of the Fusion 2040 programme. After reaching scientific gain in laser-driven ICF experiments at the National Ignition Facility, there is a global endeavour to turn the scientific milestone into practical application. The IGNYTe project addresses the currently unresolved challenge of creating an efficient ultraviolet (UV) light source that can suppress spurious nonlinearities in direct drive fusion target compression. As part of the IGNYTe team, you will develop a laser comprised of a shapeable incoherent fibre front-end, low-temperature cooled Joule-class Yb:YLF amplifiers and novel broadband third-harmonic generation schemes. The positions will be limited by default to two years, but we are seeking for candidates who are motivated to contribute longer to the project.
About your role:
- Laser development position
- Design, simulate and set-up cryogenically cooled solid-state regenerative and multi-pass Yb:YLF laser amplifiers
- Implement intelligent control over spectral and temporal shapes of broadband nanosecond laser pulses
- Broadband UV-generation position
- Push the frontiers of nonlinear optics in multi-pass cells
- Optimize third harmonic generation in nonlinear gases
- Develop scaling concepts to kJ pulse energy levels
- General tasks
- Collaborate closely with other laser research groups at DESY and with our international partners
- Integrate your developments into the control system of the facility and advance their technology readiness levels (TRLs) as far as possible
- Present your work on conferences and in scientific publications
Good reasons to join:
- Advance one of the hottest topics in laser science and collect experience in the rapidly growing fields of optics and photonics
- Contribute to highly important fusion energy research
- Work in an excellently equipped research centre with cutting-edge laboratories and on-site computer clusters
- No teaching requirement, you can spend your working time for research
Look forward to a unique working environment on our international research campus. Respectful cooperation and the well-being of our DESY employees are particularly important to us. Gender equality is an important aspect for us. You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision. As a public funded employer, we offer you a secure workplace and facilitate your individual career with our comprehensive training and development opportunities. Remuneration is according to the regulations of the TV-AVH. DESY offers its employees a financial supplement for a German job ticket (Deutschland-Ticket) at both locations.
Limited: 2 years
About you:
- Ph.D. degree in physics, optics or related fields
- A least three years of laser laboratory hands-on experience, more is a plus
- Profound understanding of pulsed laser science and/or perturbative nonlinear optics
- Team player with good communication skills
- Good command of English
- High motivation to work on the project
