Magnetotactic bacterial populations studied with a Pound-Drever-Hall atomic magnetometer
MarÃa Hernández Ruiz, Christopher Kiehl, Vito Giovanni Lucivero +1
We demonstrate an optically pumped magnetometer that monitors spin polarization using Pound Drever Hall (PDH) technique. The instrument exhibits a noise floor of 22.2 pT/sqrt(Hz) l…

Cavity-enhanced detection of spin polarization in a microfabricated atomic vapor cell
MarÃa Hernández Ruiz, Yintao Ma, Hana Medhat +3
We demonstrate continuous Pound-Drever-Hall (PDH) nondestructive monitoring of the electron spin polarization of an atomic vapor in a microfabricated vapor cell within an optical r…

Laser-written micro-channel atomic magnetometer
Andrea Zanoni, Kostas Mouloudakis, Michael C. D. Tayler +4
We demonstrate a sensitive optically-pumped magnetometer using rubidium vapor and 0.75 amg of nitrogen buffer gas in a sub-mm-width sensing channel excavated by femtosecond laser w…
