Laser applications to chemical, security, and environmental analysis: introduction to the feature issue

Abstract

The 19th Topical Meeting on Laser Applications to Chemical, Security, and Environmental Analysis (LACSEA) was held in Toulouse, France from 15-19 July 2024, as part of the Optica Optical Sensing Congress, with a return to in-person attendance. The meeting featured 21 sessions covering recent advances in laser and optical spectroscopy, sensor design, and diagnostic application. A total of 125 contributed and invited papers were presented during the meeting, including topics such as photo-acoustic spectroscopy, ultra-fast (fs/ps) laser spectroscopy, frequency comb spectroscopy, infrared imaging, sensor development, remote sensing, environmental monitoring, reacting flow diagnostics, hypersonic flow diagnostics, nuclear diagnostics, and machine learning and computational sensing.
