Abstract

Soliton molecules, composed of closely arranged pulses with strong internal interactions, have been extensively investigated in fiber lasers due to their fascinating evolutionary dynamics and potential applications in advanced optical applications. In this work, based on a passively mode-locked fiber laser, we demonstrate the characteristics of phase oscillations of various soliton molecules, including single phase oscillation and partial oscillation of the relative temporal separation in three sub-pulses to form unique evolutionary patterns. Numerical simulations reproduce the critical experimental phenomena and illustrate the oscillation behavior of soliton molecules as well as the universality of their existence. This work is of great significance for in depth understanding of the complex dynamic behavior of solitons in fiber lasers, manipulation of multiple parameters of soliton molecules and exploring potential application value.
