Atom optics under microgravity places stringent requirements on the deployed laser systems in terms of reliability, robustness, weight, volume and power consumption. Within this project, new technologies are developed which meet these demands to support experiments performed within the QUANTUS project at the drop tower in Bremen and make future sounding rocket missions feasible. For the latter, a compact glassceramic based splitting module is developed to allow for reliable switching and modulation of laser light for the generation and manipulation of ultracold Rubidium. Furthermore, a frequency comb system in a form factor suitable for microgravity platforms is currently in its design phase. Such a system paves the way for tests of the universality of free fall using a dual species atom interferometer.
The project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi)under grant number DLR 50WM 0938.
