Micro-integrated extended cavity diode lasers for precision quantum sensors — •Christian Kürbis¹, Erdenetsetseg Luvsandamdin¹, Max Schiemangk^1,2, Andreas Wicht^1,2, Götz Erbert¹, Achim Peters^1,2, and Günther Tränkle¹ — ¹Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik, Gustav-Kirchhoff-Str. 4, 12489 Berlin, Germany — ²Humboldt-Universität zu Berlin, Institut für Physik, Newtonstr. 15, 12489 Berlin, Germany

Portable cold atom based quantum sensors like atom interferometers for inertial navigation sensors, geophysics and resource exploration as well as precision quantum optics experiments in space put stringent requirements on the performance and the compactness of the corresponding laser sources. Beside narrow linewidth emission and single-mode operation at a specific wavelength the lasers have to be compact, robust, lightweight and energy efficient.

We report on the electro-optical characterization of micro-integrated extended cavity diode lasers (ECDLs) as well as on the results of mechanical stress tests carried out for future sounding rocket experiments on rubidium and potassium.
