Bose-Einstein Condensate and Cold Atom Laboratory (BECCAL) is a multi-user facility designed for operation on the ISS. This DLR and NASA collaboration 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.

A ground-based replicate of the apparatus must also be built to support the operation of the experiment. The size, weight, and power constraints of such a Ground-based Test Bed (GTB) are relaxed, and so the laser system may be made from Commercial Off-The-Shelf (COTS) components. The design of this GTB laser system will be presented alongside the design of the flight hardware for a direct comparison.

This work is supported by the DLR with funds provided by the BMWK under grant number 50WP2102.
