Compact diode laser system for dual-species atom interferometry with Rb and K in space — •Oliver Anton1, Klaus Döringshoff1, Vladimir Schkolnik1, Simon Kanthak1, Benjamin Wiegand1, Moritz Mihm3, Ortwin Hellmig4, André Wenzlawski3, Patrick Windpassinger3, Markus Krutzik1,2, Achim Peters1,2, and The MAIUS Team1,2,3,4,5,6 — 1Institut für Physik, HU Berlin — 2Ferdinand-Braun-Institut, Berlin — 3Institut für Physik, JGU Mainz — 4ILP, Universität Hamburg — 5ZARM, Universität Bremen — 6IQO, Leibniz Universität Hannover
The MAIUS 2/3 missions will perform dual-species atom interferometry with BEC’s onboard sounding rockets, enabling longer, uninterupted timescales of microgravity than any ground based facility. As a result of increasing microgravity times beyond the typical earthbound limits, future missions with dual-species atom interferometry will allow for high-precision tests of Einsteins’s Equivalence principle.
This talk presents the design of our laser system for this mission in detail and shows first performance test results. The laser sources are extended cavity diode laser (ECDL), master oscillator power amplifier (MOPA) modules emitting at wavelengths of 780 nm and 767 nm for Rb and K as well as 1064 nm for a dipole trap. Key components such as micro-integrated high power diode lasers, optical fiber splitter system and Zerodur benches will be presented.
