Special Issue Information
Dear Colleagues,
The technology of (ultra-) high-precision laser spectroscopy is revolutionizing analytical capabilities across scientific and industrial domains, enabling the development of unprecedented sensitivity, selectivity, and spatiotemporal resolution. Recent advances in laser sources, detector design, and computational methods have pushed detection limits to parts-per-trillion levels, unlocked real-time multi-component analysis, and facilitated miniaturization for field-deployable instrumentation. This Special Issue seeks to showcase cutting-edge research and innovative applications leveraging these technological leaps.
Topics of interest include, but are not limited to, the following areas:
Advanced Techniques: developments in tunable diode laser absorption spectroscopy (TDLAS), cavity-enhanced methods (e.g., CRDS, ICOS), photoacoustic spectroscopy (PAS), and surface-enhanced Raman spectroscopy (SERS) for trace detection.
Cross-Disciplinary Applications:
- Environmental Monitoring: The quantification of greenhouse gases (CO2, CH4), pollutants, and isotopic signatures with quantum cascade lasers and novel resonator designs.
- Medical Diagnostics: Breath analysis for disease biomarkers (e.g., sub-ppb sevoflurane detection via PAS) and pharmaceutical monitoring.
- Industrial Safety and Security: Explosives detection, chemical threat identification, and process control using miniaturized multi-gas sensors.
Enabling Technologies: AI-driven noise suppression (e.g., neural networks for TDLAS), terahertz time-domain spectroscopy (THz-TDS) for ultrafast material dynamics, and engineered substrates for SERS hotspot optimization.
Fundamental Advances: The mitigation of spectral broadening effects and novel materials for enhanced light-matter interactions.

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. Applied Sciences 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.
