讲座内容:

Laser spectroscopy provides many possibilities for multi-disciplinary applications in environmental monitoring, biomedicine, and energy research. Ultrasensitive and reliable trace gas sensors are required in environmental science to measure air pollutants, as well as in biomedical research to identify biomarkers related to particular diseases and metabolic disorders. Non-intrusive gas sensors are required in combustion systems to monitor key species in processes to understand the combustion fundamentals or to ensure safety and efficiency. This talk reviews our recent innovations in laser spectroscopic techniques with a multiscale and multidimensional span from absorption to dispersion, photoacoustics to photothermal, and free-space to waveguide.
