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

Applications of modern cold-atom physics in metrology and space-borne research demand for both robust and compact scientific apparatus. The project LASUS focuses on the development of the needed technology, namely miniaturized and robust diode lasers, optical modules and electronics, sophisticated for application in microgravity environments. In this poster we present the modular FPGA-based electronics for a complete atom-optical experiment, fitting in a volume of less than a few liters. These electronics allow for a fully automated laser locking system to enable autonomous operation without human intervention. The LASUS project is a collaboration of FBH Berlin, HU Berlin, U Hamburg and LU Hanover supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number 50WM1239.
