Launched in December 2023, the MAIUS-2 mission investigates BEC-mixtures of Rb and K in microgravity environment on a sounding rocket flight. To assure stable performance of the optical system under the harsh launch conditions, fiber-coupled optical benches were manufactured based on the glass ceramic Zerodur, a material which excels in having a very low coefficient of thermal expansion (CTE), as well as a high mechanical strength. Successful implementation of this optical technology was shown in various missions, such as FOKUS, KALEXUS, as well as its predecessor MAIUS-1.
MAIUS-2 represents new challenges to the optical technology, since light to manipulate both atomic species has to be intensity controlled, pulse-shaped and fiber-coupled to realize the experimental goals.
In this submission, we will present the performance of the Zerodur optical technology during the launch and flight of the MAIUS-2 mission.
MAIUS is supported by the German Space Agency DLR with funds
provided by the Federal Ministry of Economic Affairs and Climate
Action (BMWK) under grant numbers 50WP1433 & 50WP2103.
