More and more quantum technologies are used in extreme environments. The operation outside the laboratory makes high demands on the experiment and especially the laser system regarding miniaturization, power consumption, mechanical and thermal stability. In our systems, optical modules consisting of Zerodur based optical benches with free-space optics are combined with fiber components. Suitability of the technology has been demonstrated in the successful sounding rocket missions FOKUS, KALEXUS and MAIUS.
Here, we report on the optical modules for a quantum gas experiment performing dual-species atom interferometry with BECs on sounding rockets. The modules are used on the one hand to stabilize the laser frequencies and on the other hand to distribute, overlap and switch the laser beams. This includes the overlap and joint fiber coupling of beams at 767 nm and 780 nm in the same polarization state to cool and manipulate atoms of both species simultaneously.
