PhD Position (m/f/d) at the Technical University of Munich - Geodetic Observatory Wettzell

PhD Position: G‑Ring Laser Research

Join the Geodetic Observatory Wettzell at the Technical University of Munich to operate and advance the world‑leading G ring laser. The project combines laser optics, precision metrology, electronics, and advanced data analysis in close collaboration with the University of Bonn and an international DFG‑funded research unit.

Project Description

The G ring laser (4×4 m) is the only instrument of its kind providing data suitable for geodetic applications. The PhD project focuses on the operation and further development of an optical frequency comb, implementation of electronics for optical readout systems, system performance optimization, and advanced data processing.

Responsibilities

• Operate, maintain, and further develop the G ring laser system.
• Operate and improve an optical frequency comb for precision metrology.
• Design and implement electronic systems for optical readout.
• Optimize system performance, including stability and sensitivity.
• Investigate and mitigate systematic effects such as backscatter.
• Develop and implement advanced data processing and analysis methods.
• Contribute to scale factor determination and calibration strategies.
• Collaborate with partners at the University of Bonn and the geodetic analysis team.
• Document results, prepare scientific publications, and present at conferences.

Requirements

• Master’s degree in physics, laser physics, electrical engineering, aerospace engineering, or related field.
• Programming skills in MATLAB and/or Python (knowledge of C++ a plus).
• Solid background in optics and laser physics.
• Knowledge of digital signal processing.
• Interest in building and operating complex experimental systems and prototypes.
• Experience with electronics, including PCB design, soldering, and component characterization.
• Experience with frequency combs or precision metrology is a plus.
• Ability to work independently and as part of an interdisciplinary team.
• Strong problem‑solving skills and a structured working style.
• Good command of written and spoken English; knowledge of German is advantageous.

Benefits

• Work with high‑end instrumentation, including the G ring laser and optical frequency comb systems.
• Research position designed to support doctoral studies and foster scientific and personal development.
• International, interdisciplinary research unit involving multiple institutions and 14 doctoral researchers.
• Flexible working hours and option to work partially from home.
• 75 % position classified according to TV‑L E13, initially limited to four years within the DFG‑funded project.
• Continuation into a post‑doctoral position may be possible.
• Position suitable for candidates with disabilities – preference given where equivalently suitable.
• Institution supports diversity and equal opportunities. Applications from women and from individuals with diverse backgrounds are strongly encouraged.
• Measures supporting family‑career compatibility offered.

Legal and EEO Statements
