Research on Rare-Earth-Doped Fiber Lasers

Dear Colleagues,

Since the first demonstration of laser operation in a nyeodium-doped phosphate fiber by Koester and Snitzer in 1964, tremendous developments in all aspects of laser performance have been achieved with rare-earth-doped optic fibers over the past six decades. Compared to other laser platforms, fiber lasers have the advantages of outstanding heat-dissipating capability, excellent beam quality, high optical conversion efficiency and high single-pass gain. Relying on the transitions between different energy levels of trivalent rare-earth ions, fiber lasers are able to produce lasers at wavelengths ranging from ultraviolet to visible/near-infrared, and even to mid-infrared. The output power levels of fiber lasers have also undergone tremendous scaling after double-clad rare-earth-doped fibers were invented. A kW-level continuous-wave output can now be easily obtained with a ytterbium-doped double-clad silica fiber. Additionally, pulsed fiber lasers employing different pulse generation techniques have also been developed and ultrashort pulses (shorter than 10 femtoseconds) have been achieved. Nevertheless, rare-earth-doped fiber lasers face many challenges for novel applications.

This Special Issue invites manuscripts that introduce the recent advances in rare-earth-doped fiber lasers. All theoretical, numerical and experimental papers are accepted. Topics include, but are not limited to, the following:

• Novel rare-earth-doped fiber lasers;
• Advanced kW-class fiber laser design and development;
• New power scaling techniques;

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.
