Laser Applications to Chemical, Security and Environmental Analysis


The LACSEA meeting focuses on new technologies for optical sensing applications, spectroscopic chemical-sensing methods, security applications, remote sensing, and tools for environmental analysis.

LACSEA addresses all aspects of optical techniques and instrumentation for chemical, security, and environmental analysis. The meeting covers diagnostics of combustion and industrial process gases, atmospheric sensing and monitoring, and the analysis of gases that may contain chemical or biological agents. Sensing of liquids (e.g., aerosols) and solids (e.g., particulates or explosives) is also discussed.

Topics include exciting new developments in analytical spectroscopy, ultrafast lasers, frequency combs, and miniaturization using optical approaches spanning the VUV to THz spectral range.
