Phd candidate Jobs in Rellingen

European XFEL is an international non-profit company located in the Hamburg area in Germany. It operates a 3.4 km-long X‑ray laser, which produces X‑rays of unique quality for studies in physics, chemistry, the life sciences, materials research and other disciplines. The diverse scientific facilities at European XFEL enable scientists from across the globe to carry out a wide range of experimental techniques.

The EuXFEL "Strategy 2030+" identifies various development programs, which are ongoing or about to start, aiming at short- to mid-term enhancements to current capabilities and user experience. It also foresees programs, with the purpose of developing or qualifying technology for a complete facility upgrade during the next decade. This upgrade will bring advanced X‑ray photon delivery modes, a higher number of pulses-per-second on sample and attosecond X‑ray pulses, to name a few features. Naturally, this demands a new generation of experimental optical drive laser source (pump-probe laser) to be developed. All laser-related needs, both mid- and long-term, will be addressed within a laser development program starting in 2025.

In particular, for the development of next generation pump-probe lasers, we are seeking to employ a

Laser Scientist (f / m / d)

Working closely with the program manager, laser-group staff and collaborators at EuXFEL and external, the candidate will :

• Lead a project team for the development of demonstrator systems of the next generation European XFEL instrument specific pump-probe laser solutions
• Perform analysis, identifying the individual optical laser requirements of the different scientific instruments in the future
• Identify suitable 1µm wavelength, high power ultrafast laser technologies for highly reliable and low maintenance 24 / 7 laser operation and qualify them
• Provide conceptual laser designs fulfilling the requirements while taking into account advanced X‑ray photon delivery modes (high duty cycle or continuous, arbitrary pulse sequences)
• Interface with other projects within the program, addressing generation and delivery of THz and tunable fs-UV radiation, based on the pump-probe laser

The project entails full proof of concept, including conversion methods (e.g. OPA, OPCPA), direct compression, timing stabilization, beamline and instrument integration, control system integration and all engineering solutions required for documented and upgrade-ready designs.

Become part of a vibrant international and multicultural team of scientists, engineers, technical and administrative staff. Be involved in cutting edge scientific and technical progress and participate in our international networks. Experience our atmosphere of tolerance and respect.

Salary and benefits are similar to those of public service organizations in Germany, this includes for example :

Our company language is English.

Reference number : S-586

Duration : This appointment is initially limited to 5 years.
