We present a new generation of compact laser systems optimized for precision measurement applications with ultra-cold atoms aboard sounding rockets. Design, assembly and qualification of a system capable of atom interferometric experiments with degenerate 87Rb in context of the MAIUS mission will be discussed. It combines micro-integrated, high power diode laser modules with a switching module based on zerodur optical bench technology and fiber optical splitter systems. All stringent qualification procedures and reliability issues imposed by a double-stage rocket mission launch have been passed on component and system level. Laser spectroscopy payloads for two other sounding rocket experiments, FOKUS and KALEXUS, are presented which demonstrate the technological readiness of complex laser system assemblies and key components for future space missions. All laser systems are to be launched within the next two years.
