In preparation for future quantum gas experiments in space, preliminary experiments are currently performed at the ZARM drop tower in Bremen and a sounding rocket mission is planned for the near future. In this context compact and robust laser systems have been developed.
An overview of the planned laser system capable of performing atom interferometry experiments will be given. The talk will present, e.g., the concepts of a hybrid integrated master oscillator power amplifier (MOPA) and a mesoscopic spectroscopy stabilized reference laser. The MOPA consists of a laser chip, an amplifier, and microoptical components all integrated on a 10×50 mm2 microbench. The reference laser combines this microbench technology with a macroscopic vapor cell.
The QUANTUS project is a collaboration of LU Hannover, ZARM at U Bremen, U Ulm, U Hamburg, and HU Berlin. It is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0835-0839.
