Special Issue Information
Dear Colleagues,
Almost since its invention, the laser has been used to cut and process materials—everything from dielectrics and metals to polymers and biomaterials. Laser micromachining offers significant advantages over many mechanical machining methods, mostly in processing quality and allowing ever smaller, more precise features. The advent of ultrashort pulsed lasers, with pulse durations on or faster than the ~1 picosecond time frame for coupling between electrons and phonons, opened a new regime of laser micromachining and microprocessing. The fundamental physics of this ultrashort pulse laser ablation process is fascinating, and not yet fully understood. From a practical standpoint, these ultrashort pulses have been heralded for their ability to “cold cut” and reduce or eliminate the heat-affected zone around the ablation feature. The microprecision and feature quality can be extraordinarily good. Unfortunately, the limited energy carried by each ultrashort pulse means that micromachining with ultrashort pulses can be very slow—currently too slow for most industrial applications. This Special Issue will explore the current state-of-the-art in understanding and applying pulsed lasers to micromachine materials and to micro- and nanoprocess their surfaces. Contributions that explore fundamental mechanistic understandings for all pulse regimes as well as those that discuss applications will be welcomed. The topics to be covered include, but are not limited to the following:
- Pulsed laser micromachining
- Femtosecond laser micromachining
- Picosecond laser micromachining
- Nanosecond laser micromachining
- CW laser micromachining
- Mechanism of laser ablation
- Laser ablation efficiency
- Micromachining with pulse bursts
- Micromachining with spatially-shaped beams
- Laser micropatterning
- Laser nanopatterning

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. 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 2600 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.
