  Important ongoing research on mode-locked fiber lasers aims at developing new
types of multi-soliton regimes, such as soliton molecules, molecular complexes
or soliton crystals. The on-demand generation of such multi-pulse structures is
a major challenge, whereas experiments generally involve a tedious
trial-and-error adjustment of the laser parameters. Here, we present an
approach based on a gradual and calibrated adjustment of the system
configuration, which employs efficient parameter routes to reach well-defined
multi-pulse regimes. Our numerical simulations show that once the mode-locking
threshold is reached, we can adjust the laser parameters gradually to force the
evolution of the laser dynamics towards multi-pulse structures with fewer
distortion in their intensity profiles, which are accessible at reduced pump
power levels.
