High Power Fiber Laser Technology

Dear Colleagues,

As one of the first kinds of lasers to be demonstrated since the invention of the laser, fiber lasers have gained a solid reputation as versatile and powerful laser machining tools. With the parallel and rapid development of high-brightness laser diodes and double-cladding fiber materials, the output power of fiber lasers spanning a wide wavelength has seen an unprecedented increase, promising a new avenue for micromachining applications. One example is the combination of extremely high beam quality fiber lasers with 3D printing technology to fabricate complicated and compound components, and these applications require higher laser power for efficient operation. However, fiber lasers at a high-power level of several kilowatts now suffer from some problems, such as mode/polarization degradation, nonlinear effects, and thermal effects, which deteriorates the beam quality and has hampered the deep integration of high-power fiber lasers with micromachines, limiting their applications. To break through the aforementioned limitations, new high-power fiber laser technology, including the new fiber laser concept, new fiber design and materials, new fiber components, and new beam combination technology, should be proposed and encouraged, and laser–matter interaction with new types of fiber lasers should be explored. Accordingly, this Special Issue seeks to showcase research papers and review articles that focus on novel methodological developments in high-power fiber lasers, i.e., the concept and physics of novel fiber lasers, the design and manufacture of fiber materials, and the fabrication of high-performance fiber components.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines 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 2100 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.
