Dear Colleagues,

Like other varieties of laser, fiber lasers consist of three parts: gain medium, pump source, and resonant cavity. Fiber lasers use active fibers doped with rare earth elements in the fiber core as a gain medium. Generally, semiconductor lasers are used as pump sources. The resonant cavity is generally composed of devices such as mirrors, fiber end faces, optical filters, or fiber gratings.

Fiber lasers possess the advantages of high output power, excellent beam quality, narrow linewidth, good heat dissipation performance, compact structure, etc., and are growing more and more important in scientific research and industrial production.

Until now, various kinds of fiber lasers have been proposed for the application of optical imaging, material processing, high-precision sensing, optical fiber communication, spectroscopy, microwave generation, laser-based medical treatments, and a variety of other uses. For example, ultra-narrow linewidth fiber lasers are attractive for usage in high-resolution acoustic sensing and 2 μm fiber lasers are interesting in atmospheric applications. Thus, this technology is of vital importance for the investigation of various kinds of fiber lasers and their wide applications.

Both original research papers and review papers are welcome. Potential technical topics include, but are not limited, to the following areas of study:

• Fiber lasers operating in various wavebands, including 1.0 μm, 1.5 μm, 2.0 μm and above;
• New mechanisms in fiber lasers, including power amplification, linewidth narrowing, wavelength tuning and so on;
• Various applications of fiber lasers in scientific research, including optical imaging, material processing, high precision sensing, optical fiber communication, spectroscopy, microwave generation, laser medical and so on;
• Application of fiber lasers in industry, including cutting, welding, marking and so on;
• Mode-locked fiber laser, wavelength tunable and switchable fiber laser and so on;
• Design and fabrication of various fibers used for emerging science and applications of fiber laser.

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.
