Compact diode laser system for dual-species atom interferometry with Rb and K on an sounding rocket — •Oliver Anton1, Klaus Döringshoff1, 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, future missions with dual-species atom interferometry will allow for high-precision tests of Einsteins’s Equivalence principle.
This poster presents the design of our laser system for this mission in detail, shows first results of frequency stability measurements and introduces the ground testbed activities in setting up a Rb/K dual-species quantum gas experiment. Key components such as micro-integrated high power diode lasers (767, 780, 1064 nm), optical fiber splitter system and Zerodur benches will be presented.
