The first production of a Bose-Einstein condensate in space carried out in the MAIUS-1 sounding rocket mission in January 2017 paved the way for more advanced experiments with ultra-cold matter in space. The goal of the MAIUS-2 mission is the creation of mixtures of ultra-cold rubidium and potassium atoms onboard a sounding rocket.
To this end, an advanced laser system was developed, that can provide the light required for simultaneous laser cooling of rubidium and potassium as well as imaging of the Bose-Einstein condensates. The system was realized and qualified to meet the demands of a sounding rocket mission.
We report on the performance of the system, its assembly process, the used technologies as well as tests carried out to assure that the laser system can face the needs of the mission.
This work is supported by the German Space Agency (DLR) with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number 50 WP 1432.
