Laser system technology for rubidium atom interferometry aboard sounding rockets — •Vladimir Schkolnik1, Markus Krutzik1, Achim Peters1,2, The MAIUS Team1,2,3,4,5, and The FOKUS Team1,2,3,4 — 1Institut für Physik, Humboldt- Universität zu Berlin — 2Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Berlin — 3ILP, Universität Hamburg — 4Institut für Physik, JGU Mainz — 5IQO, Leibniz Universität Hannover
Laser systems with precise and accurate frequencies are one of the key elements in modern precision experiments such as atom interferometers and atomic clocks. Future space missions including quantum interferometry based gravity mapping, tests of the equivalence principle or the detection of gravitational waves will need robust and compact lasers with high mechanical and frequency stability.
We present a new generation of compact diode laser systems optimized for precision measurement applications with ultra-cold atoms aboard sounding rockets. Design, assembly and qualification of the laser system for the MAIUS mission, an atom interferometer with degenerate 87Rb scheduled for launch 2016 is discussed.
All key technologies have already been successfully tested on a separate sounding rocket mission in 2015 by performing precision Doppler free spectroscopy in space on the TEXUS 51 mission. The payload and the experimental results are presented.
