Compact diode laser system for dual-species atom interferometry with Rb and K in space — •Oliver Anton1, Klaus Döringshoff1, Vladimir Schkolnik1, Simon Kanthak1, Markus Krutzik1, Achim Peters1, and The MAIUS Team1,2,3,4,5 — 1Institut für Physik, Humboldt-Universität zu Berlin — 2Ferdinand Braun Institut, Leibniz-Institut für Höchstfrequenztechnik, Berlin — 3ZARM, Universität Bremen — 4Institut für Physik, JGU Mainz — 5IQO, Leibniz Universität Hannover
The MAIUS II/III missions will perform dual-species atom interferometry with BEC’s onboard sounding rockets, enabling longer, uninterupted timescales of microgravity than any other ground based facility. By therefore effectively increasing interferometer times beyond the typical limits imposed by, for example, the maximum height of terrestrial instruments, MAIUS II/III will allow for high-precision measurements of Einsteins’s Equivalence principle.
This poster presents the design of our laser system for this mission in detail. All key components such as micro-integrated high power diode lasers, optical fiber splitter system and Zerodur bench technology will be highlighted. The laser sources are exetended cavity diode laser (ECDL) master oscillator power amplifier (MOPA) modules. They feature wavelengths of 780 nm and 767 nm for Rb and K as well as 1064 nm for a dipole trap.
