Dual-comb is currently attracting attention for realization of high-speed, high-resolution spectroscopic measurements. In the anomalous dispersion region, there have been problems with broadband and high sensitivity due to Kelly sidebands and other effects. To solve this problem, we have developed an all-polarization-maintaining dual-comb fiber laser in the normal dispersion region. Using SWNTs as saturable absorbers, we succeeded in achieving dual dissipative soliton mode-locking. In addition to the evaluation of the characteristics, the mutual stability was confirmed experimentally.
