Abstract

Low coherent pulse bound states have drawn significant interests due to their distinctive structures and dynamic behaviors. Single- or dual-wavelength interference-induced noise-like soliton molecules (NLSMs) characterized by the crossing features of a broad autocorrelation pedestal of noise-like pulses (NLPs) and symmetrically distributed autocorrelation multi-spikes of soliton molecules (SMs) are experimentally achieved in a fiber laser with a dualcavity structure, respectively. The generation of NLSM owes to the intrapulse interference within an NLP or interpulse interference between two NLPs, exhibiting its coherence varying from weak to strong. Moreover, the coherent pulse spacing within NLSMs can change from 8.42 to 44.93 ps by altering length differences between two subcavities. Our work provides a novel approach for manipulating low coherent pulse generation.
