Special Issue Information
Dear Colleagues,
Laser spectroscopy represents a cornerstone in the development of advanced, high-performance detection systems. The use of laser sources combined with spectroscopic techniques enables precise, selective, and sensitive detection of molecular species that can be tailored to address a wide range of environments. Techniques such as Tunable Diode Laser Absorption Spectroscopy (TDLAS), cavity-enhanced spectroscopy (in all its possible variations and implementations), comb spectroscopy, Raman scattering, Laser Induced Breakdown Spectroscopy (LIBS), and photoacoustic spectroscopy have demonstrated exceptional capabilities in gas sensing, biomedical diagnostics, environmental monitoring, and industrial process control. Recent advancements in Quantum Cascade Lasers (QCLs), Interband Cascade Lasers (ICLs), and frequency combs have pushed the limits of mid-infrared and terahertz sensing, enhancing both resolution and miniaturization. Moreover, the integration of spectroscopic platforms with fiber optics, advanced detectors, and photonic integrated circuits is enabling the development of portable, field-deployable systems. This synergy between laser technology and advancements in optics, spectroscopy and optoelectronics is key to meeting current and future challenges in trace detection, multi-species analysis, real-time monitoring and remote sensing.
We invite authors to submit original research, new developments, experimental works, and surveys in the fields of spectroscopic-based techniques for gas sensing, with possible applications to process control, environmental monitoring, health and safety, and agrifood industry. The topics of interest of this Special Issue include, but are not limited to the following:
Tunable diode laser absorption spectroscopy
Cavity enhanced spectroscopy
Comb spectroscopy
Raman spectroscopy
Laser induced breakdown spectroscopy
Photoacoustic spectroscopy
Trace detection
Multi species analysis
Remote sensing

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. Sensors 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 2600 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.
