We present stability tests of laser system components for atom interferometry in microgravity within the QUANTUS and LASUS projects. Special challenges in the construction of the laser system are posed by the vibrations and accelerations found during the launch phase of sunding rockets or in droptower experiments. Compact subcomponents and an integrated subsystem consisting of a fiber coupled master-oscillator power amplifier (MOPA) have been tested under extreme conditions to investigate their mechanical stability. These tests are especially crucial for developing a laser system for further experiments in space.
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.
