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

30.06.2026, Academic staff

Join the Geodetic Observatory Wettzell at the Technical University of Munich and contribute to the operation and further development of the world-leading G ring laser. This PhD 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

At the Technical University of Munich, within the Geodetic Observatory Wettzell, we operate the 4 × 4 m G ring laser — currently the only instrument of its kind providing data suitable for geodetic applications. This PhD project focuses on the operation and further development of an optical frequency comb, as well as on the implementation of electronics for optical readout systems. The work includes system operation, continued development, and performance optimization. The successful candidate will collaborate closely with the quantum metrology group at the University of Bonn and the geodetic analysis team, contributing to data generation, processing, and delivery. The project will address key challenges such as advanced backscatter mitigation, improved scale factor estimation, and advanced post-processing. A background in physics or engineering, ideally with some experience in laser optics, digital signal processing, and electronics, is an advantage. More about the Ring project can be found: www.ringlaser.de Requirements
