The precision of inertial measurements has been tremendously increased with the advent of cold atom-based interferometers. Space missions which allow higher precision of such instruments rely on the laser system, dedicated to cool and manipulate the atoms.
Subsequent to successful previous sounding rocket missions, we report on a laser system for rocket missions performing dual-species atom interferometry with BECs. Core elements of the laser system are optical benches and fiber-optical elements used on the one hand to distribute, overlap and switch the laser beams and on the other hand to stabilize the laser frequencies. In order to withstand the harsh conditions during flight, we use the glass ceramic Zerodur providing high mechanical and thermal stability. A Zerodur-based test bench for the qualification of new components has been assembled, characterized and tested under flight conditions. Currently, the flight hardware is built and characterized prior to integration.
