Zerodur-based optical systems for precision measurements in space — •André Wenzlawski1, Moritz Mihm1, Kai Lampmann1, Ortwin Hellmig2, Klaus Sengstock2, Patrick Windpassinger1, and the MAIUS Team1,2,3,4,5,6 — 1Johannes Gutenberg-Universität Mainz — 2ILP, Universität Hamburg — 3Institut für Physik, HU-Berlin — 4IQO, Leibniz Universität Hannover — 5ZARM, Universität Bremen — 6FBH, Berlin
Stable and robust optical systems are a key technology for high precision experiments such as atom interferometers or atomic clocks. Future space missions which allow for key improvements in these fields additionally require a high degree of thermal and mechanical robustness for the individual components.
To fulfill these requirements we developed a number of optical systems based on the glass ceramic Zerodur, a material which excels in having a very low coefficient of thermal expansion (CTE) over a very broad temperature range.
We present different fiber-coupled modules whose functionalities range from spectroscopy of Rubidium or Potassium to intensity control and pulse shaping for the MAIUS-experiments realizing a BEC-based atom interferometer.
MAIUS is part of the QUANTUS project, which is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant numbers DLR 50 WM 1131 - 1137 and DLR 50 WP 1431 - 1435.
