In the ongoing quantum revolution of science, many current studies aim to bring quantum systems to market maturity, such as quantum computers and quantum sensors. Ongoing efforts attempt to increase the accessibility of such systems, while minimizing size, mass and power requirements.
We previously demonstrated the succesful use of stable optical and laser systems based on the glass ceramic Zerodur in space borne atom interferometry experiments, e.g. FOKUS, KALEXUS and MAIUS.
On this poster, we present current developments of Zerodur to metal vacuum flanges, enabling accessible, yet mechanically and thermally stable vacuum systems. Furthermore, we report on the ongoing effort of the construction of a passively pumped Zerodur vacuum chamber for quantum sensoric applications, using optical activation of passive pumps and atom dispensers to demonstrate a MOT.
Our work is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Climate Action (BMWK) under grant numbers 50WM2266B, 50WP1433 & 50WP2103.
