Combined Pulse Laser: A Reliable Tool for High-Quality, High-Efficiency Material Processing

Dear Colleagues,

With wide applicability and low-cost processing advantages, laser processing, as a mature and versatile tool, is forming an alternative to conventional processing technologies. In recent years, combined pulse laser (CPL), one of the hybrid laser processing technologies, has proven to be a reliable tool for high-quality and high-efficiency processing through the processing advantages of different types of lasers and controlling the laser–matter interaction.

The basic idea of using CPL to process materials is to improve the material removal rate (MRR) by controlling the temporal or spatial profiles of CPL to meet the different laser energy requirements during the laser–matter interaction. Thus, the CPL method has driven the exploration to optimize the laser–matter interactions, and started the race toward these and many other attractive goals. Up to now, the ideas of developing CPL have been explored for improving the efficiency and quality of laser processing in a wealth of applications, such as ablation, drilling, welding, cutting, cleaning, and annealing.

This Special Issue aims at presenting original state-of-the-art research articles dealing with the fundamentals and application of the CPL processing methods. Researchers are invited to submit their contributions to this Special Issue. Topics include, but are not limited to, the following:

• Theoretical analysis of the CPL–matter interaction;
• Evolution of CPL-excited plasmas;
• Multiple types of applications for CPL processing methods;
• Process study of CPL processing;
• Temporal and spatial shaping CPL processing methods;
• Multi-timescale in situ observations of CPL processing.

We look forward to receiving your contributions.

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.
