We present the design and implementation of semiconductor laser modules that are suitable for quantum optical experiments in space. We report on the integration of two arbitrary laser chips, micro-optics, DC and HF electronics including fiber-coupling into a single-mode, polarization maintaining fiber on a structured AlN-substrate with a footprint of 80 x 30 mm². Moreover, we present the packaging of the AlN-substrate into a hermetically sealed housing with custom-made feedthroughs for all DC, HF and optical signals. Results of mechanical vibration and shock tests, as well as thermal cycling tests on sub-assemblies of the laser modules are shown. We present the electro-optical performance of a Master Oscillator Power Amplifier (MOPA) module with a distributed feedback laser (DFB) as master oscillator operating on the above-named technology platform.
