BECCAL (Bose-Einstein Condensate and Cold Atom Laboratory) is a cold atom experiment designed for operation on the ISS. It is a DLR and NASA collaboration, built on a heritage of sounding rocket and drop tower experiments, and NASA's CAL. This multi-user facility enables the exploration of fundamental physics with Rb and K BECs and ultra-cold atoms in microgravity, facilitating prolonged timescales and ultra-low energy scales. In contrast to lab-based cold atom experiments, BECCAL must be operable without interference for three years on the ISS. To reach that goal and match the complexity of this space-based system to the stringent size, weight, and power limitations, we have to fulfill strict product assurance requirements for the laser system including higher cleanliness facilities and ESD protection. In this context, the planning and implementation of the specific lab setup and the first essential integration tests, using mock-ups, will be presented. This work is supported by the DLR with funds provided by the BMWK under grant numbers DLR 50WP1702, and 50WP2102.
