Many nonlinear systems exhibit solitons, localized excitations balanced by dispersion and nonlinearity, which also can bind together in so-called soliton molecules. Here, we study the behavior of soliton molecules in a mode-locked laser oscillator. By employing the time-stretch dispersive Fourier transform (TS-DFT), we experimentally access the previously hidden internal dynamics of soliton molecules, tracking their pulse separation and relative phase in real-time. A diverse set of dynamical trajectories is observed, including periodic oscillations of the pulse separation and relative phase [1]. Moreover, we actively drive internal vibrations over a range of frequencies and amplitudes. We identify internal resonances of the soliton molecules and detect higher harmonic and subharmonic responses.
