KALEXUS - a potassium laser system with autonomous frequency stabilization on a sounding rocket. — •Aline Dinkelaker1, Max Schiemangk1, Vladimir Schkolnik1, Andrew Kenyon1, Markus Krutzik1, Achim Peters1,2, and The KALEXUS Team1,2,3,4,5 — 1Institut für Physik, Humboldt-Universität zu Berlin — 2FBH Berlin — 3JGU Mainz — 4LU Hannover — 5Menlo Systems GmbH
Atomic physics experiments on space-borne microgravity platforms require robust laser systems that can be frequency stabilized for applications such as laser cooling or atom interferometry. Additionally, the systems should work autonomously as access and communication are usually limited. Sounding rockets provide a suitable test environment for such technologies. With the KALEXUS experiment we have created a compact, robust and modular system that includes two extended cavity diode lasers (ECDLs) with an optical switch, an absorption spectroscopy setup and its own on-board computer and control electronics. The system is designed to autonomously perform absorption spectroscopy, frequency stabilization and tests of redundancy components on-board the TEXUS 53 sounding rocket. KALEXUS specifically tests the performance of two micro-integrated ECDLs with one laser stabilized to 39K and a second, offset locked laser. We present an overview of the experiment, its components and operation.
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.
