Special Issue Information

Dear Colleagues, 

Advances in active optical fibers, laser architectures, and beam shaping technologies have improved the performance of fiber laser systems, including output power, laser conversion efficiency, beam quality, and operational stability. These developments have broadened the scope of fiber laser applications in precision manufacturing, biomedical engineering, laser communication, military, and remote sensing. This Special Issue is dedicated to high-quality submissions focusing on the design, optimization, and applications of fiber laser systems. Research areas may include (but are not limited to) the following:

  • High-power continuous-wave or pulsed fiber lasers;
  • Ultrafast fiber lasers;
  • Coherent and spectral beam combination;
  • Advanced laser parameter controlling technologies;
  • Industrial, medical, and scientific applications of fiber lasers;
  • Laser plasma technologies.

We welcome submissions of original research articles and reviews. We look forward to receiving your valuable contributions.

Prof. Dr. Haitao Zhang
Guest Editor

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. Applied Sciences 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.

A novel approach for laser coherent beam combination (CBC) utilizing the self-imaging effect in plasma waveguides is presented in this study, which enables the transmission of ultrashort laser pulses at intensities above the bulk damage threshold of conventional solid optical waveguides. The feasibility of self-imaging-based CBC in plasma waveguides was simulated and verified, demonstrating favorable combining efficiency and beam quality. This work explores the adaptive tuning of waveguide length via dynamic adjustment of plasma density, addressing the critical issue of fabrication tolerances in traditional waveguide systems. With CBC via plasma waveguide, this study offers support for the development of robust, high-power laser systems with enhanced beam quality and operational stability. Full article
