A tunable laser system for imaging of rubidium at high magnetic fields

 Jennifer Koch – Diploma in Physics


My diploma thesis comprised the planning and construction as well as the integration of a laser system for the absorption imaging of ultracold rubidium clouds in high external magnetic fields. The planning particularly included the design of the laser system for the given physical applications. Therefore, calculations were carried out which describe the behaviour of the rubidium atoms in an external magnetic field.


Since my work extends from planning to application, the required skills were very versatile. Therefore, I was able to extend my knowledge in programming, electrical and optical design as well as data analysis.

Interaction of Individual Ultracold Cs Atoms with a Rb Quantum Gas

Steve Haupt – Master of Science in Physics


My project included -

  • The independent operation of a quantum gas lab with the conception of independent research projects and data acquisition, including the setup and alignment of laser systems
  • Analysis of experimental data and numeric modelling of the system in the programming language python
  • Regular presentation of results in the research group


  • Getting Started/literature research: 10 %
  • Setup of optics and electronics: 10 %
  • Running the experiment and data acquisition in the lab: 35 %
  • Data analysis and programming: 25 %
  • Writing up the thesis: 20 %


Working on a quantum gas experiment requires a diligent, precise and methodical working attitude and is rewarded with (partly) worldwide unique measurements and results. I specially liked the combination of idependency and responsibility for small projects (experiment and analysis) and the team orientation on the experiment. Already very soon, one gets the chance to co-decide on important steps for the experiment‘s future.

Preparations for driving Feshbach resonances on ultracold Rubidium and Caesium atoms

Manuel Stein – Diploma Physics


In my diploma thesis, I have been working towards Feshbach resonances on the Boson experiment. In this context I was dealing with microwave manipulation of atomic states, so I got in touch with high frequency technology – a completely new field for me.


Due to the duration of the thesis project I had to practice documenting my work – a very valuable skill. In contrast to the advanced lab classes the work required the close coordination with the other students on the experiment, and even more persistence – however, this allowed to dig very deep
