Dual comb spectroscopy,Soliton mode-locked fiber laser

In this study, we successfully implemented an all-polarization maintaining, soliton mode-locked, fiber laser using single-walled carbon nanotubes (SWNTs). The laser employs a mechanical sharing concept to achieve high mutual coherence. It has a repetition frequency of 70.9 MHz and a frequency difference of approximately 100 Hz. We conducted the experiments of dual comb spectroscopy for hydrogen cyanide (HCN) gas and observed the corresponding absorption spectra.
