The impact you will make

As a key contributor at the forefront of high-power laser fusion science, you will play a pivotal role in shaping the future of laser technology, driving innovations that redefine energy generation. Collaborating with multidisciplinary teams and leading experts worldwide, your work will directly influence cutting-edge fusion concepts. This is a hands-on opportunity to grow in a dynamic, multinational environment while making a lasting impact on sustainable energy.

Your responsibilities

Build, operate and stabilize the frequency-comb front end — set up, run, lock and maintain the comb source in the lab.
Build, stabilize and characterize cavities — assemble, align, lock and optimize the reference and enhancement cavities.

Carry out the hands-on lab work of the subsystem — alignment, troubleshooting, measurement and optimization, working independently.

Work with the multidisciplinary team to integrate your subsystem with the amplification, synthesis and other advanced technologies into the overall system design.

Utilize common laser diagnostic and nonlinear techniques to measure and analyze ultrafast pulses.

Document experimental procedures, results, and design recommendations in a structured and traceable manner

Contribute to the continuous improvement of the laser system, diagnostics and workflows.

Contribute to laser-operation procedures and safety protocols and ensure compliance with safety standards.

Master's degree or PhD in Physics, Optical Engineering, Laser Engineering, Photonics, or a related field.
Experimental expertise across ultrafast-laser sources — diode-pumped solid-state, short-pulse and fiber lasers and amplifiers — and their diagnostics.
Practical experience with optical alignment, laser operation, and laboratory troubleshooting.
Hands-on experience in optical frequency combs and their stabilization
Hands-on experience with high-finesse optical cavities — alignment, locking, mode-matching, and finesse/loss optimization
Practical experience with locking electronics and feedback/servo loops
Programming and data-analysis skills (e.g. Python) for measurement automation and analysis.
Strong analytical and problem-solving skills with a structured approach to technical challenges
A hands-on, self-driven and collaborative working style — you enjoy digging into complex problems with attention to detail in a dynamic, multidisciplinary team.
Excellent written and verbal communication skills in English
