Potassium Spectroscopy on a Sounding Rocket — •Kai Lampmann1, Ortwin Hellmig5, Markus Krutzik2, Achim Peters2,3, André Wenzlawski1, Patrick Windpassinger1,5, and The KALEXUS Team1,2,3,4 — 1Johannes Gutenberg-Universität, Mainz — 2Humboldt-Universität zu Berlin — 3Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Berlin — 4Leibniz Universität Hannover — 5Universität Hamburg
We present the laser system of the sounding rocket experiment KALEXUS. This mission is scheduled to be launched in spring 2016 and should demonstrate the fully autonomous operation of a system for laser frequency stabilization, which is required e.g. 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 options to handle possible system failures.
The spectroscopy module for absolute frequency stabilization to the potassium D2 line consists of special monolithic Zerodur components for guiding and overlapping the beams. A fiber based splitting module connects the different functional units of the system and provides a beat note detection for offset frequency stabilization. We show ground based characterization measurements of the spectroscopy system and tests for space qualification.
The KALEXUS project is led by the Humboldt-Universität zu Berlin and 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.
