Beschreibungen/Notizen

• We present here an experimental demonstration of dual-comb spectroscopy performed around 2 µm, with the use of a new design of dispersion-controlled highly nonlinear fibre. The latter allows us to efficiently convert light via a four-wave mixing process from 1.55 µm to 2 µm, which is a spectral region suited for the detection of pollutants such as CO 2 or N 2 O. Experimental measurements have been performed with these two molecules and show an excellent agreement with the HITRAN database.
