BECCAL (Bose-Einstein Condensate--Cold Atom Laboratory), a mul- ti-user facility designed for operation on the ISS, is a DLR and NASA collaboration built on the heritage of NASA's CAL, sounding rocket and drop tower experiments. Fundamental physics will be explored with Rb and K BECs and ultra-cold atoms in microgravity, at longer time- and ultra-low energy scales compared to those achieved on earth. The laser system design provides a reliable and robust combination of micro-integrated diode lasers (from FBH) and miniaturized free-space optics on Zerodur boards (from JGU), interconnected with fiber optics, to meet the unique challenge of matching the complexity of the required light fields to the stringent size, weight, and power limitations on the ISS. An update one the BECCAL laser system design will be given based on the requirements, concepts, and heritage which formed it. Funding by DLR / BMWK grant numbers 50 WP 2102, 2103, 2104.
