This manuscript 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 response, as well as expected magnetometer performance merits and how they are affected by main sources of noise. This is followed by a brief comparison of different magnetometer realizations and an overview of current research, with the aim of helping readers to identify the most suitable magnetometer type for specific applications. Next, we discuss some practical considerations for experimental implementations, using the case of an M z magnetometer as an example of the design process. Finally, an interactive workbook with real magnetometer data is provided to illustrate magnetometer-performance analysis.

“…Notably, a review paper highlighted the progress of electromagnetic induction imaging (EMI) with atomic magnetometers, indicating that EMI technology has entered a new phase of development with real-word applications now within reach. [10] Furthermore, AMAs are used in various applications, including the testing of magnetic materials, [11] functional magnetic imaging of humans, [12][13][14] monitoring of the Earth's magnetic field, [15] and detecting biomagnetic signals with high spatial resolution. [16] Researchers have emphasized that using a magnetometer with a single-beam setup effectively simplifies the optical paths by combining the pump and probe light into a single beam.…”

Using spin‐exchange relaxation‐free (SERF) atomic magnetometer array (AMA) in magnetocardiography and magnetoencephalography has presented a challenge in reducing its packing volume for integrated instrumentation and convenient maintenance. This study presents a novel, space‐saving SERF AMA based on an 8‐channel planar lightwave circuit (PLC) waveguide splitter with a compact footprint of 26 × 2.5 mm2. The PLC splitting configuration allows the synchronization of the pump for a multisensor array, resulting in highly consistent performance among the sensors, with an impressive ultrahigh sensitivity of 34 fT Hz−1/2 within a measurement bandwidth of 105 Hz. The PLC splitting method shows great promise in expanding the channel capacity of small‐scale SERF AMAs, offering a cost‐effective method for high‐resolution medical diagnoses through functional magnetic imaging of humans. In addition, this method is expected to find applications in fields such as electromagnetic induction imaging, biological magnetism, and geomagnetic observation.

“…Recent work [4] demonstrated that electromagnetic induction imaging (EMI) with atomic magnetometers (AMs) [5]- [7] can identify and quantify localized thinning of metal plates, thus opening up an alternative viable route for imaging of corrosion under insulation. EMI-AMs is advantageous for CUI imaging with respect to existing techniques: it is simple and low cost, it does not involve ionising radiation, thus being completely harmless, and retains its capability at low frequency, which results in a significant penetrating power both through insulating material as well though the pipeline core structure.…”
