Zerovak: Compact and portable vacuum and laser system technology for cold atom experiments — •Nora Bidzinski¹, Bojan Hansen¹, David Latorre Bastidas², André Wenzlawski², Patrick Windpassinger², Ortwin Hellmig¹, and Klaus Sengstock¹ — ¹Institute for Quantum Physics, University of Hamburg, 22761 Hamburg, Germany — ²Institut für Physik, Johannes Gutenberg-Universität Mainz, 55099 Mainz, Germany

Performing ultra cold atom experiments outside a laboratory environment such as mobile platforms or space applications requires a compact and energy-efficient experimental setup.

Hence, we present a novel flange-free ultra-portable vacuum chamber without the necessity of an active getter pump. Choosing Zerodur, a glass ceramic with low helium and hydrogen permeability as well as very low thermal expansion coefficient, ensures maximum stability against thermal fluctuations due to environmental changes.

Further, we propose a compact and highly miniaturised laser system for cooling atoms including a method for substituting AOMs while maintaining full functionality.
