Experimental atom optics under conditions of microgravity places stringent requirements on the deployed laser systems in terms of reliability, robustness, weight, volume and power consumption. We present new technologies which meet these demands in order to support ongoing experiments performed within the QUANTUS project at the drop tower facility in Bremen and make future sounding rocket missions feasible. For the latter, a compact glass-ceramic based splitting module is developed to allow for reliable switching and modulation of laser light for the generation and manipulation of ultracold Rubidium. Furthermore, a frequency comb system is currently in its design phase. To this end, micro-optically integrated diode lasers covering the spectral range from 767 nm to 780 nm are currently being developed. Such a system paves the way for future tests of the universality of free fall using a dual species atom interferometer.
The LASUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0938.
