Progress in Ultra-Stable Laser Source and Future Prospects

Dear Colleagues,

An ultra-stable laser is a high-performance optical frequency oscillator, which boasts advantages such as low frequency noise, narrow linewidth, and excellent coherence.

Ultra-stable lasers are widely used in fundamental scientific fields such as gravitational wave detection, gravitational redshift measurement, relativistic tests, high-precision spectroscopy, and very long baseline interferometry. They also have important applications in industrial fields such as laser gyroscopes, navigation and communication, laser ranging, coherent communication, and optically generated ultra-stable microwave sources.

This Special Issue aims to provide a broad overview of the research trends in ultra-stable lasers, with a particular emphasis on advancements in stable laser sources and future prospects. We invite researchers to submit manuscripts to this Special Issue. Research areas may include (but are not limited to) the following:

• Optical cavity;
• Optical frequency transfer;
• Optical frequency comb;
• Atomic clock;
• Fiber-stabilized laser;
• Gravitational wave detection;
• Quantum network;
• Precision measurement of Rydberg atoms;
• Optical microcavity.

We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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.
