A graphene-nanotube mode-locked tandem fiber laser with a chirped fiber Bragg grating (CFBG) is proposed, for the first time to our best knowledge. This laser is composed of two resonators with opposite net dispersions, and it delivers a conventional soliton (CS) and a dissipative soliton (DS) simultaneously. The CS operated in a net-anomalous-dispersion cavity has a spectral width of similar to 0.59 nm and a pulse duration of similar to 5 ps, and the DS is operated in another cavity with a pulse duration of similar to 15.3 ps. By using a piece of single-mode fiber, the DS can be compressed to similar to 6.5 ps, while the CS is gradually broadened up to similar to 9 ps.
