Frequency Comb Spectroscopy

Mid-IR frequency combs enable detection of molecular species showing absorption in the important molecular fingerprint region between 500 cm-1 and 4000 cm-1 (2.5–20 μm). Examples include the detection of pollutants such as ozone, methane, carbon monoxide, nitric oxide or biomarkers indicating malignoma or other severe diseases. Our current research focuses on high spectral resolution frequency comb spectroscopy.
