Special Issue Information

Dear Colleagues,

Advances in laser spectroscopy have enabled many scientific breakthroughs and applications in physics, chemistry, biology, and scientific research. This Special Issue addresses the advancements in atomic and molecular spectroscopy, particularly in the application and development of laser spectroscopy technology. In recent years, detection technology using laser spectroscopy has made significant advancements in various fields. In the qualitative and quantitative analysis of sample detection, laser-induced fluorescence spectrum (LIS), laser Raman spectroscopy (LRS), and laser absorption spectroscopy (LAS) technologies have significant advantages in both detection accuracy and response speed. In addition, the combination of laser spectroscopy and imaging technology further expands the fields of application, such as laser spectral imaging (LSI) and the laser confocal microscope (LCM). Papers in these research areas will be presented in the upcoming Special Issue.

This Special Issue invites manuscripts that introduce the recent advances in laser spectroscopy. All theoretical, numerical, experimental, and application-oriented papers are accepted. Topics include, but are not limited to, the following:

  • Novel laser spectroscopy techniques;
  • Laser-spectroscopy-based fiber sensing techniques;
  • Laser-spectroscopy-based remote sensing;
  • Advances and applications of laser measurements;
  • Infrared laser techniques;
  • Recent advancements in tunable laser techniques.

As the signature gas released before coal combustion, methane’s telemetry accuracy is susceptible to environmental influences, which is a difficult problem that needs to be solved. This article provides a detailed exposition on the application of Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology in the field of gas monitoring, with particular emphasis on its advantages in coal safety detection. The coal combustion experiment is conducted to determine the required performance indexes. Through the temperature compensation algorithm and normalized signals, the impact of factors such as ambient temperature and environmental noise is reduced, effectively improving the signal-to-noise ratio and accuracy. The experiments demonstrate that this system effectively lowers the detection limit for methane while improving measurement accuracy, thereby providing robust support for the early warning of coal spontaneous combustion.
