Probe-assisted Depopulation Pumping in Low-pressure Alkali-metal Vapor Cells for Magnetometry

M. E. Limes, J. Smoot, J. Perez +4

For precision atomic magnetometry, inert buffer gas is included in alkali-metal vapor cells to significantly broaden hyperfine transitions, which facilitates optical pumping and re…

Frequency-dependent amplitude correction to free-precession scalar magnetometers

M. E. Limes, L. Rathbun, E. L. Foley +3

Pump and probe scalar atomic magnetometers show incredible potential for real-world, traditionally difficult measurement environments due to their high dynamic range and linearity.…

Long spin-1/2 noble gas coherence times in mm-sized anodically bonded batch-fabricated He-Xe-Rb cells

M. E. Limes, N. Dural, M. V. Romalis +4

As the only stable spin-1/2 noble gas isotopes, He and Xe are promising systems for inertial rotation sensing and searches for exotic spin couplings. Spin-1/2 noble g…

Pulsed Vector Atomic Magnetometer Using an Alternating Fast-Rotating Field

Tao Wang, Wonjae Lee, Mark Limes +3

We introduce a vector atomic magnetometer that employs a fast-rotating magnetic field applied to a pulsed Rb scalar atomic magnetometer. This approach enables simultaneous m…

Heading errors in all-optical alkali-vapor magnetometers in geomagnetic fields

W. Lee, V. G. Lucivero, M. V. Romalis +3

Alkali-metal atomic magnetometers suffer from heading errors in geomagnetic fields as the measured magnetic field depends on the orientation of the sensor with respect to the field…

Portable magnetometry for detection of biomagnetism in ambient environments

M. E. Limes, E. L. Foley, T. W. Kornack +6

We present a method of optical magnetometry with parts-per-billion resolution that is able to detect biomagnetic signals generated from the human brain and heart in Earth's ambient…
