Description
Despite the availability of commercial multi-gas detectors, identifying unknown gases on-site in case of industrial accident like fire, remains challenging due to smoke's complex composition and detectors cross-sensitivity. Infrared laser spectroscopy, based on the measurements of ro-vibrational transitions of IR-active molecules, is a well-known technique inherently selective and capable of performing non-invasive and quantitative gas detection in harsh environments. In this talk, we will discuss infrared laser spectroscopy techniques for in situ and remote sensing, focusing on requirements for an infrared laser spectrometer for identifying and quantifying multiple gases at ppm levels. Specifically, we'll spotlight the use of a new picosecond mid-IR Optical Parametric Oscillator (OPO) based laser source and share the results obtained in the case of in situ and remote sensing measurements carried in the lab and on the field.
