Optical Applications of Mid-Infrared Lasers

Dear Colleagues,

Since the invention of the laser in 1960, there has been a commitment to extending its visible and near-infrared wavelength to both ends of the spectrum. With the emergence of various mid-infrared (mid-IR) laser sources, including solid-state, chemical, gas, semiconductor, and nonlinear frequency generation, various mid-IR laser technologies and applications have developed rapidly. Typically, mid-IR is considered to cover the wavelength range of 2.5–25 μm; this region is significant for applications such as the laser absorption spectroscopy of trace gases (e.g., medical diagnostics and remote sensing in environmental monitoring). There are also applications in non-metal laser material processing because of the ongoing development of more powerful mid-IR laser sources, e.g., fiber lasers. Recently, ultrashort pulses and frequency combs in the mid-IR region have attracted significant interest. However, the development of the mid-IR laser still faces many challenges from technical and engineering aspects.

This Special Issue invites manuscripts that introduce the recent advances in “Mid-Infrared Lasers”. All theoretical, numerical, and experimental papers will be accepted. Topics include, but are not limited to, the following:

• Mid-infrared laser sources, such as quantum cascade lasers, lead salt lasers, and doped insulator bulk lasers;
• Nonlinear frequency conversion;
• Mid-infrared fiber sources;
• Mid-infrared laser materials;
• Mid-infrared detection and recognition technology;
• Mid-infrared integrated optoelectronic technology;
• Mid-infrared imaging;
• Mid-infrared frequency combs.

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.
