Special Issue Information
Dear Colleagues,
Atomic magnetometers (AMs) are highly sensitive devices for measuring magnetic fields based on atomic quantum properties. They operate by detecting the interaction among light, atoms, and magnetic fields. Compared with traditional magnetometers, atomic magnetometers offer much higher sensitivity, reaching sub-femtotesla levels. They can accurately measure weak magnetic fields in real time. These magnetometers find wide applications: In biomedicine, they are used for magnetocardiography and magnetoencephalography to detect biological magnetic signals. In geophysics, they help in exploring underground resources by detecting magnetic anomalies. In space research, they measure the magnetic fields of planets and stars. However, the development of atomic magnetometers will face many challenges regarding the technical and engineering aspects in enhancing the sensitivity and accuracy of atomic magnetometers to meet the demands of diverse applications.
This Special Issue invites manuscripts that introduce recent developments in “Advancements in Optical Techniques for Enhancing the Sensitivity and Precision of Atomic Magnetometers”. All theoretical, numerical, and experimental papers are accepted. Topics include, but are not limited to, the following:
- Atomic polarization and measurement of the polarizability;
- Method for detecting atomic precession signal;
- Precision dispersion compensation and measurement;
- Generation and optimization of the optical field for polarization and detection;
- High-precision magnetic field compensation technology;
- Atomic magnetometer noise suppression technology;
- Atomic vapor cell heating and temperature control;
- Optical methods for improving the sensitivity and precision of atomic magnetometers;
- Methods of laser modulation and optical field optimization;
- Design and application of array-type atomic magnetometers;
- High-precision three-axis atomic magnetometer.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Photonics is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
