Job summary

Fusion Energy Base is seeking a highly skilled researcher to lead hands-on work with ultrafast laser systems in Munich. You will build and stabilize frequency-comb front ends, align and lock high-finesse cavities, and integrate subsystems with amplification and synthesis in a collaborative, multinational environment.

The role requires hands-on lab experience with ultrafast lasers, diagnostics, and Python for data analysis.

Qualifications

• Master's degree or PhD in Physics, Optical Engineering, Laser Engineering, Photonics, or a related field.
• Hands-on experience with ultrafast laser sources and diagnostics.
• Experience with optical alignment and laser operation.

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 reference and enhancement cavities.
• Carry out hands-on lab work of the subsystem — alignment, troubleshooting, measurement and optimization.
• Collaborate to integrate the subsystem with amplification and synthesis into the system design.
• Use laser diagnostics to measure ultrafast pulses and document results.
• Contribute to safety procedures and quality workflows.

Job description

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.

What you bring

• 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.
