Abstract
A dual comb spectrometer is used as gas sensor for the parallel detection of nitrous oxide (N2O) and carbon monoxide (CO). These gases have overlapping absorption features in the mid-infrared (MIR) at a wavelength of 4.6 µm. With a spectra acquisition rate of 10 Hz, concentrations of 50 ppm N2O and 30 ppm CO are monitored with a relative precision of

Ein Doppel-Frequenzkamm-Spektrometer wird für die parallele Detektion von Lachgas (N2O) und Kohlenstoffmonoxid (CO) verwendet. Die Gase weisen überlappende Absorptionen im mittleren Infrarot (MIR) bei einer Wellenlänge von 4.6 µm auf. Die Akquisitionsrate der Spektren von 10 Hz erlaubt es die Konzentrationen von 50 ppm N2O und 30 ppm CO mit einer relativen Genauigkeit von

M. Sc. Leonard Nitzsche studied physics at the Albert-Ludwigs-University in Freiburg and received his M. Sc. in 2017. Since 2017 he is working at Fraunhofer IPM in Freiburg, Germany and is a PhD student at the Albert-Ludwigs-University in Freiburg with the research focus on dual comb spectroscopy for process applications.
M. Sc. Jens Goldschmidt received his M. Sc. in Microsystems Engineering at the Albert-Ludwigs-University of Freiburg in 2019. He has been working at Fraunhofer IPM in Freiburg, Germany, from 2019 to 2021, where he dedicated his work to the development of a dual frequency comb spectrometer. Since 2021 he is a PhD student at the Albert-Ludwigs-University in Freiburg in the field of spectroscopy with broadband light sources.
Dr. Armin Lambrecht graduated in physics at University of Karlsruhe in 1985. Since 1986 he has been working at Fraunhofer IPM in Freiburg, Germany. Starting with molecular beam epitaxy for mid infrared lasers he later focused on infrared sensors systems for gas and liquid process analysis. He retired after many years of experience as R&D project manager, department head and business developer, but still works part-time at Fraunhofer IPM.
Prof. Dr. Jürgen Wöllenstein studied electrical engineering at the University of Kassel until 1997. He is head of department for gas and process analytics at Fraunhofer IPM and leads the laboratory for gassensors at the Albert-Ludwigs-University in Freiburg, department of Microsystems Engineering IMTEK.
