Raw Data for: Fast rate dual-comb spectrometer in the water-transparent 7.5-11.5 μm region

This repository shares the data acquired and used to produce the figures in the paper "Fast rate dual-comb spectrometer in the water-transparent 7.5-11.5 μm region" published in Optics Letters (DOI: https://doi.org/10.1364/OL.515199)

The "Figure_Data" zip file contains a ".txt" file for each Figure present in the Main Paper and Supplemental Document. The raw data acquired by the FT spectrometer and uploaded here for Figure 2 are afterward smoothed and normalized properly in the Main Paper to better show the spectra. Data shown in Figure 3 are calculated from the corresponding raw data.  Data used for Figure 4 are calculated from the corresponding raw blank DCS data. Data for Figure 5, 6 and S1 are retrieved from the corresponding raw Gas DCS data upon Cepstral removal of the spectral baseline and spectral fit exploiting the Hitran Database.

The "Raw_Data" zip file contains the postprocessed Data of the DCS measurements and the RIN data as acquired. The Raw data of the DCS measurements as acquired are too large to be uploaded here, but may be obtained from the authors upon request.
"NH3_1o6kHz_IGMmean", "N2O_5o1kHz_IGMmean", "N2O_26kHz_IGMmean" contain the DCS interferogram averaged over 15s of acquisition for Gas measurements, performed with different DeltaFrep as described in the main text of the paper.
"Blank_1o6kHz_IGMs", "Blank_5o1kHz_IGMs", "Blank_26kHz_IGMs" contain all the phase corrected DCS interferograms acquired over 100ms, used to calculate the average SNR shown in Figure 4.
"RIN_DFG" contain the raw data acquired from the detector for RIN calculations, with an average voltage values of 25mV.

The scripts for processing the Raw Data and retrieve the data as shown in the paper are home made.
