Potassium Spectroscopy on a Sounding Rocket — •Kai Lampmann1, Ortwin Hellmig5, Achim Peters2, Patrick Windpassinger1,5, and The KALEXUS Team1,2,3,41Institut 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, special monolithic Zerodur components are used for fiber coupling the laser light and within the spectroscopy module for guiding and overlapping the beams and mounting the spectroscopy cell including the heating necessary for potassium. Furthermore, a fiber based splitting module is set up to connect the different functional units of the system and to provide an offset frequency stabilization.

The KALEXUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number 50 WM 1345.
