Dual comb spectroscopy has attracted much attention in recent years because of its fast data acquisition time, high resolution and broadband spectroscopy. This study aims to realise high sensitivity in dual comb spectroscopy by using an all-polarization-maintaining dual-comb fiber laser with mechanically sharing configuration at a repetition rate of 100 MHz to reduce the EDFA noise and improve the number of integration cycles.
