Laser Scientist (f/m/d)

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, 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 candidate who 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, beam line and instrument integration, control system integration and all engineering solutions required for documented and upgrade-ready designs.

Minimum Requirements:

• A degree and PhD in photonics, applied physics or a similar discipline.
• A broad theoretical and practical knowledge base and proven hands on experience with all relevant high power and ultrafast laser technologies and the associated measurement and characterization methods.
• At least 5 years of project and leadership experience in academia, industry or both. Successfully completed projects will support the application.
• Excellent communication and collaboration skills and the ability to work in a multi-lingual, multi-disciplinary team, with English as the working language. Knowledge of German is considered an asset.

Become part of a vibrant international and multi-cultural 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:

• Family friendly working environment (e.g. additional childcare days).
• Flexible working times and option for work from home depending on tasks.
• 30 days of vacation, 24th and 31st of December are free as a courtesy of the employer.
• Extensive relocation benefits.
• Generous company pension scheme (6,45% of monthly salary).
• Monthly social events and subsidized company restaurant.
• Partially financed job-tickets for public transportation.
• Extensive training opportunities incl. subsidized English and German language classes.
• Easy and free access to a mental health platform to support your wellbeing.

Our company language is English.
