We present the synchronization of two all-fiber mode-locked lasers, operating at $1.0\mathrm{\mu m}$ and $1.54\mathrm{\mu m}$ , coupled through the use of a shared single-wall carbon nanotube absorber. Both lasers operate in the soliton-regime, achieving a synchronized repetition rate of $13.08\mathrm{MHz}$ . The broadband absorption range of the single-wall carbon nanotubes allows the stable mode-locking behavior at $1\mathrm{\mu m}$ and $1.5\mathrm{\mu m}$ . The nonlinear coupling effects between two energy states of the carbon nanotube absorber result in stable synchronized pulses for hours of operation, with a large cavity mismatch of $1400\mathrm{\mu m}$ .
