This article is designed as a step-by-step guide to optically pumped magnetometers based
on alkali atomic vapor cells. We begin with a general introduction to atomic magneto-optical …

In the early 1980s, researchers at NASA's Jet Propulsion Laboratory in California realized
that stable reference signals generated by a hydrogen maser atomic clock could be …

Understanding the relationship between brain activity and specific mental function is
important for medical diagnosis of brain symptoms, such as epilepsy …

Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can
form stable, macroscopic field configurations in the form of topological defects that could …

In recent years diode laser sources have become widespread and reliable tools in magneto-
optical spectroscopy. In particular, laser-driven atomic magnetometers have found a wide …

We demonstrate an all-optical magnetometer capable of measuring the magnitude and
direction of a magnetic field using nonlinear magneto-optical rotation in cesium vapor …

Here we demonstrate an atomic magnetometer that has a bandwidth of more than 100 kHz
and a sensitivity of 180 fT/√ Hz at a Fourier frequency of 8 Hz, and 0.7 nT/√ Hz at 100 kHz …

We compare the sensitivity performance of two optically pumped atomic magnetometers
based on the Mx and frequency-modulated bell-bloom configurations. The Cs …

We present a laser-based atomic magnetometer that allows inferring the modulus of a
magnetic field from the free Larmor precession of spin-oriented Cs vapour atoms. The …

A scalar magnetic field sensor based on a millimeter-size Rb87 vapor cell is described. The
magnetometer uses nearly copropagating pump and probe laser beams, amplitude …
