Zerodur based laser systems for precision measurements in micro-gravity — •Mona Rafipoor1, Hannes Duncker1, and the LASUS Team1,2,3,4 — 1Institut für Laser-Physik, U Hamburg — 2Institut für Physik, HU Berlin — 3Ferdinand-Braun-Institut, Berlin — 4Institut für Quantenoptik, LU Hannover
Ballistic rockets provide several minutes of micro-gravity and thereby promise to improve the precision of interferometric measurements with matter waves. However, a rocket launch poses stringent requirements on the employed components in terms of thermal and mechanical stress yet to be met by commercial products. To pave the way for the next generation of quantum precision experiments in micro-gravity, e.g. on sounding rockets, we developed laser system technology based on Zerodur within the project Lasus. The components and integrated systems benefit from the vanishing thermal expansion of Zerodur and its mechanical robustness.
The LASUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number 50WM1238.
