Special Issue Information
Dear Colleagues,
High-energy pulsed lasers are advanced optical devices capable of generating extremely intense laser pulses with durations ranging from femtoseconds to nanoseconds. These lasers have revolutionized numerous scientific, industrial, and medical fields due to their unique ability to deliver concentrated energy in ultrashort timeframes. The development of pulsed lasers can be traced back to the invention of the laser itself in 1960, with subsequent advancements in Q-switching and mode-locking techniques enabling the production of high-power pulses. Today, they are indispensable in applications requiring precision, high peak power, and minimal thermal damage, such as laser machining, nuclear fusion research, and biomedical surgery.
The operational principle of high-energy pulsed lasers relies on the controlled release of stored energy in a gain medium. Key technologies include Q-switching, which produces nanosecond pulses by modulating the laser cavity’s quality factor, and mode-locking, enabling femtosecond pulses via phase synchronization of longitudinal modes. Chirped pulse amplification (CPA), a Nobel Prize-winning technique, further boosts peak power by stretching, amplifying, and compressing pulses to avoid optical damage. These methods allow pulsed lasers to achieve terawatt or even petawatt peak powers, far exceeding continuous-wave lasers.
The forthcoming Special Issue will highlight advances in high-energy pulsed lasers, including Q-switching, mode-locking, and CPA techniques. We cordially invite authors to contribute original research articles and review articles highlighting recent breakthroughs and future perspectives in high-peak-power laser development and utilization.

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. Nanomaterials 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.
