In this study, the experimental observation of stable soliton molecules in a dispersion-managed dissipative fiber laser system employing a MoS2-based saturable absorber is reported. The laser cavity, designed with a thulium-doped fiber gain medium and dispersion-shifted fibers, generates bound pulse pairs at 1.9 μm with a constant inter-pulse separation of 1.7 ps. Real-time dispersive Fourier transform measurements reveal periodic vibrational dynamics, manifested as coherent oscillations in both temporal separation and relative phase between constituent solitons, mimicking the behavior of chemical molecules. This robust dynamical stability over thousands of cavity round trips demonstrates the potential of soliton molecules for advanced applications in ultrafast optical communications and photonic logic processing.
