Special Issue Information
Dear Colleagues,
High-power ytterbium (Yb)-doped optical fibers and lasers have rapidly advanced, exerting a substantial influence across diverse scientific and engineering disciplines. Current challenges in high-power fiber lasers primarily arise from optical nonlinearities and thermal management constraints. Narrow-linewidth lasers (linewidth < 0.3 nm) are predominantly limited by Stimulated Brillouin Scattering (SBS), whereas broadband lasers are constrained by Stimulated Raman Scattering (SRS). Transverse mode instability (TMI) restricts the power of all single-mode and quasi-single-mode high-brightness fiber lasers. Mitigation strategies targeting these nonlinear effects involve fiber and system design optimizations, including passive and active control methods, to further enhance laser power. Recent advances in thermal management, such as tandem pumping configurations, have enabled the stable, long-term operation of tens of kilowatt class fiber lasers in continuous-wave industrial applications.
This Special Issue highlights recent progress in high-power fiber lasers, particularly Yb-doped systems. The scope includes advancements in nonlinear effect suppression, polarization-maintaining fiber lasers, ultra-high-power fiber laser development, and specialty fiber design. Acknowledging the impact of artificial intelligence (AI) tools like deepseek and ChatGPT on research productivity, this Special Issue also welcomes submissions showcasing novel AI applications in related research domains.

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.
