In this study, hydrogen cyanide (HCN) gas absorption spectroscopy was conducted using an all-polarization maintaining (PM) single-cavity dual comb fiber laser. The research focused on utilizing dual-comb spectroscopy (DCS) to enhance measurement speed and resolution, comparing favorably with traditional Fourier transform spectroscopy. By employing a 25-fold averaging technique, the experiment significantly improved the signal-to-noise ratio, thereby enhancing the precision of spectral data.
