Compact and robust design of a crossed optical dipole trap for space application — •Jan Simon Haase1, Janina Hamann1, Alexander Fieguth2, Jens Kruse2, Carsten Klempt1,2, and The INTENTAS Team1 — 1Institut für Quantenoptik, Leibniz Universität Hannover, Welfengarten 1, 30167 Hannover — 2DLR Institut für Satellitengeodäsie und Inertialsensorik, Callinstraße 30b, 30167 Hannover
Towards the implementation of atom interferometry in commercial sensors, improvements of the current systems in compactness and robustness are a next necessary step. Also, for applications in space it is urgent to compactify the sensors and make them robust against accelerations and vibrations.
In the INTENTAS project (Interferometry with entangled atoms in space) evaporative cooling in a novel, optical dipole trap will be used to create Bose-Einstein condensates in a microgravity environment. The project will demonstrate a compact source of entangled atoms in the Einstein-Elevator, a microgravity platform which allows zero-gravity tests for up to 4 s. The planned experiments will pave the way to employ entangled atomic sources for high-precision interferometry in space applications.
In this talk, the novel design of the optical dipole trap is presented. Simulations of the beam deformation and measurements from first flight tests are shown.
