We demonstrate high-resolution magnetic field imaging using a custom micro-machined cesium (Cs) vapor cell filled with nitrogen (N$_2$) buffer gas [1], incorporating automated spatial sampling via a two-axis MEMS scanning mirror. The cell utilizes advanced fabrication techniques that enable flexible and scalable geometries, making it well suited for a variety of applications, including...
Microfabricated alkali vapor cells are central to the development of compact and low-power atomic devices such as atomic clocks and optically pumped magnetometers (OPMs). However, conventional microfabrication techniques, particularly those relying on anodic bonding for final sealing, impose high temperatures that are incompatible with the integration of antirelaxation coatings.
In this work,...
Anti-relaxation coating (ARC) vapor cells are a critical component in atomic physics and quantum sensing, yet their widespread adoption is hindered by short spin coherence times and low manufacturing yields, stemming from the lack of systematic preparation protocols. Herein, we present an in-situ monitoring system that enables real-time optimization of the spin coherence time and vapor density...
Optically pumped magnetometers (OPMs) are revolutionizing the task of magnetic-field sensing due to their extremely high sensitivity combined with technological improvements in miniaturization which have led to compact and portable devices. OPMs can be based on spin-oriented or spin-aligned atomic ensembles which are spin polarized through optical pumping with circular or linear polarized...
