Solitons can form bound states that are frequently referred to as soliton molecules as they exhibit molecule-like dynamics. The build-up phase of the optical soliton molecule remains elusive. Here, by means of a time-stretch technique that enables real-time access to the spectral and temporal dynamics, rich nonlinear processes involved in the build-up of soliton molecules are revealed in an ultrafast fibre laser. Specifically, the formation of closely- and well-separated bound solitons are resolved. In both cases, the build-up phases consist of three nonlinear stages including mode locking, soliton splitting, and soliton interactions. For closely-separated bound solitons, soliton interactions display wide diversities in repeated measurements, including soliton attraction, repelling, collision, vibration, and annihilation. For well-separated bound solitons, repulsive interactions dominate the soliton interactions. Numerical simulations corroborate these experimental observations. Furthermore, a conceptually different soliton molecule, the intermittent-vibration soliton molecule, is discovered and characterized. It is the intermediate state between the vibrational and stationary soliton molecules. The author's findings could assist in the understanding of the build-up phase of localized structures in different dissipative systems.
