Microgravity environments such as a sounding rocket or a satellite can greatly benefit a number of quantum optics experiments. These experiments often entail a compact and lightweight laser system that can withstand high thermal fluctuations and mechanical stress. To this end, we have developed a technology based on fibre-coupled optical benches made from Zerodur, a glass-ceramic that exhibits a near zero coefficient of thermal expansion, onto which free-space optical components are glued. We have successfully used this toolkit for the creation of a BEC in the scope of the MAIUS-1 sounding rocket mission and will further use it for the upcoming MAIUS-2/3 and the NASA-DLR Bose-Einstein Condensate and Cold Atom Laboratory (BECCAL) mission aboard the ISS. For the latter we have adapted our toolkit, making our system even more compact. Our work is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) under grant number 50 WP 1433 and 50 WP 1703.
