The research activities of the Laser Spectroscopy group are focused on the development and application of high precision trace gas analyzers for environmental, industrial and medical applications. Relying on state of the art mid-infrared laser sources, e.g. continuous wave quantum cascade lasers (QCLAS), we cover the whole mid-infrared spectral range (3-10 µm) which gives us highest flexibility, sensitivity and specificity.
We close the gap between research grade and field deployable laser based instrumentation by combining high-performance with compactness, robustness, autonomy and modularity. This results in mobile sensors capable for in situ and continuous analysis of single or multiple molecular species under field conditions. High-precision gas measurements are the key to answer specific research questions and advance our knowledge in many important areas related to climate, environment, agriculture and medical diagnostics.
Our research projects include the measurement of trace gas fluxes for CO2, N2O, CH4 and NO2, the determination of isotope ratios of CO2, N2O and CH4 in ambient air, and breath air analysis for clinical research.
