Special Issue Information
Dear Colleagues,
Fiber lasers have experienced remarkable development in recent decades, positioning themselves as one of the most versatile and efficient technologies for generating laser radiation across a wide spectral range. In particular, the 1-2 µm wavelength region has gained significant relevance due to its wide-ranging applications in telecommunications, materials processing, medicine, spectroscopy, and remote sensing. This issue addresses the most recent advances in the design, underlying physics, and implementation of fiber lasers operating within this spectral window, encompassing continuous wave (CW) sources as well as pulsed systems based on Q-switching and mode-locking techniques. In addition, emerging ultrafast modulation methods are considered, which enable laser emission to be tailored to specific requirements in terms of power, pulse duration, and repetition. Current technological challenges and the strategies adopted to improve the efficiency, stability, and compactness of these systems are also discussed, especially compared to competing technologies that do not rely on saturable absorbers. Collectively, these developments underscore the key role of fiber lasers as adaptable and high-performance platforms for next-generation scientific and industrial applications.

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. Electronics is an international peer-reviewed open access semimonthly 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.
