Atom interferometry in space is gaining ever-increasing interest because of the accessible interrogation times exceeding what is possible on ground by orders of magnitude and thus allowing unprecedented sensitivities. This may enable more precise tests in fundamental physics like a test of the equivalence principle or detection of gravitational waves.
As a first step towards realizing atom interferometry based precision measurements in space, the sounding rocket MAIUS-I was launched this winter from northern swedish Esrange demonstrating the technological and scientific feasibility of these kind of experiments.
Here we will present the optical system for the MAIUS-I experiment, used to cool and manipulate an ensemble of 87Rb atoms as well as the scheme for autonomous frequency stabilization of the lasers with respect to a hyperfine transition of 85Rb.
The MAIUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) under grant numbers 50WM1131-1137.
