Potassium Spectroscopy on a Sounding Rocket — •Kai Lampmann1, Ortwin Hellmig5, Achim Peters2, Patrick Windpassinger1,5, and The KALEXUS Team1,2,3,4 — 1Institut für Physik, Johannes Gutenberg-Universität, Mainz — 2Institut für Physik, HU Berlin — 3Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Berlin — 4Institut für Quantenoptik, LU Hannover — 5Institut für Laserphysik, U Hamburg
We present a laser spectroscopy system for the sounding rocket experiment KALEXUS. The KALEXUS experiment aims at demonstrating a completely autonomously operating laser spectroscopy system for quantum gas experiments in space. The whole system is designed to meet the stringent requirements of a sounding rocket launch and to provide redundancy for autonomous operation during the whole flight.
To this end, the spectroscopy module for laser frequency stabilization consists of special monolithic Zerodur components for guiding and overlapping the beams. We show ground based characterization measurements and tests for space qualification of the spectroscopy system and the fiber based splitting module, which connects the different functional units of the system and provides an offset frequency stabilization.
The KALEXUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) under grant number 50 WM 1345.
