Applications of Laser Spectroscopy

Dear Colleagues,

Over 60 years after the realization of the first laser in 1960, laser spectroscopy is still a very intense field of research that has expanded with remarkable progress into many areas of science, medicine, and technology and has provided an ever-increasing number of applications. The importance of laser spectroscopy and its appreciation by many people is, for instance, proved by the fact that over the last ten years, three Nobel prizes have been awarded to nine scientists in the field of laser spectroscopy and quantum optics. Moreover, laser spectroscopy continues to develop and expand rapidly. Many new ideas and recent realizations of new techniques based on old ideas have contributed to the progress in many fields.

This Special Issue focuses on the most recent research and development related to a relatively broad category on laser spectroscopy. We would like to give space to recent progress of laser spectroscopy benefited from new laser sources, novel optical design, advanced spectroscopic principles, improved measuring techniques, and prosperous applications across a variety of fields. This Special Issue welcomes high-quality original research or review papers reporting the latest spectral technologies and their applications, especially those revealing the prospective opportunities offered by the unique features of laser spectroscopy, in a wide range of topics including but not limited to the following:

• Advanced laser spectroscopy-based sensing technologies;
• Novel optical design for laser spectral systems;
• Innovative electronic circuits for improving spectral systems;
• Development of laser spectroscopy-based gas sensing systems;
• Applications of spectral/hyperspectral imaging techniques;
• Ocean applications of optical sensors.

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. 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.
