In various fields of fundamental physics and metrology, inertial sensors based on matter waves are continuously gaining importance. The sensitivity of matter wave interferometers is mainly limited by the free expansion time of the ultra-cold sample, their ultimate sensitivity can only be reached in space. In this poster we present advanced laser systems for high precision quantum gas experiments on different microgravity platforms like drop tower capsules, sounding rockets and satellites. Special challenges in the construction of the particular laser systems are posed by the challenging and tough environment, putting stringent requirements on the performance of laser sources. Diode-laser based systems have been developed, which successfully passed mechanical stability tests (50g) and vibration tests, that simulate mechanical loads of a sounding rocket launch (8 gRMS).
The QUANTUS and LASUS project are supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM 1131-1137 and 0937-0940.
