Compact electronics for laser system in microgravity — •Thijs Wendrich, Wolfgang Ertmer, and Ernst Maria Rasel — Leibniz Universität Hannover, Institut für Quantenoptik

Microgravity experiments with ultra cold degenerate quantum gases require very compact and robust apparatuses. The LASUS project develops miniaturized and robust diode lasers, optical modules and electronics for use in the drop tower in Bremen and in space. In this poster we present the FPGA-based electronics for a complete experiment, fitting in a volume of less than a few liters. These electronics allow for a fully automated laser locking system to enable long term operation without manual intervention outside the lab. The LASUS project is a collaboration of FBH Berlin, HU Berlin, U Hamburg and LU Hannover supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number 50WM1239.
