Autonomous experiments with ultra cold quantum gases on microgravity platforms can place fundamental physics in a unique position to adress some of the most significant questions of modern science, such as testing the weak equivalence principle. As an important next stepping stone with regard to space qualification, MAIUS aims at realizing Bose-Einstein condensates and investigating its coherence properties onboard a double-stage sounding rocket. In this poster, we present the current status of our laser system in detail. Special challenges in the construction are posed by the extreme environment, putting stringent requirements in terms of robustness, miniaturization and redundancy. All critical subsystems successfully passed mechanical vibration tests, that simulate the mechanical loads of a sounding rocket launch.
The QUANTUS and LASUS project are supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant numbers DLR 50 WM 1131-1137 and 1237-1240.
