Investigation of diffraction gratings and additively manufactured vacuum components for miniaturized atomic physics packages — •Alisa Ukhanova, Marc Christ, Conrad Zimmermann, Jörg Fricke, Olaf Brox, Robert Smol, Daniel Bandke, Jenichi Clairvaux Felizco, Andrea Knigge, and Markus Krutzik — Ferdinand-Braun-Institut (FBH), Leibniz-Institut für Höchstfrequenztechnik, Berlin

Atom-based quantum devices allow precise timekeeping and field sensing. The application of these sensors beyond the laboratory environment requires improvements of size, stability and user-friendliness. Here, we are developing a technology toolbox towards miniaturized cm-scale physics package. In this presentation we show results of the optical qualification of diffraction gratings for GMOTs with varying periods, duty cycles and coatings. Furthermore, 3D-printed ceramic and aluminum components for vacuum applications are investigated and a next generation compact physics package envisioned.

This work is supported by FBH and partially supported by the German Space Agency (DLR) with funds provided by the Federal Ministry for Economic Affairs and Climate Action (BMWK) due to an enactment of the German Bundestag under grant number 50WM1949 and 50WM2070.
