High-Power Infrared Laser Systems: Design, Characterization, and Applications

Dear Colleagues,

Over the past twenty years, the sources of infrared lasers and their applications have undergone tremendous development. Starting with solid infrared lasers, using the technology of nonlinear optical frequency conversion, quantum cascade lasers and semi-conductor lasers, mid-infrared fiber lasers, and infrared lasers are becoming more compact and more powerful. At present, those infrared lasers are still flourishing. Solid lasers based on Ho- and Er-ion-doped materials are increasing in output power. Functional PPLNs are making infrared lasers more versatile, while ZGP and BGSe are extending the spectrum range of infrared lasers. Nowadays, mid-infrared fiber lasers based on ZBLAN are becoming practicable. Thanks to the development of ultra-fast laser technologies, ultra-fast infrared lasers and mid-infrared combs based on synchronized pumping techniques or mid-infrared fiber laser technology are driving infrared lasers to be more sophisticated. In recent years, the source of infrared lasers based on chip is frequently reported. This type of infrared source combines laser technology and waveguide fabrication, often utilizing chips made from Si or LNOI. Infrared chips are advantageous for modulation and compactness; these characteristics make chip-based infrared sources highly promising.

On the other hand, with the advancement of infrared laser sources, a multitude of applications for infrared lasers have been explored. Nowadays, infrared lasers are extensively employed in material processing, medical applications, remote sensing, communication and scientific research.

In conclusion, the distinctive properties of infrared laser have significantly broadened technological possibilities across various domains.

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. 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.
