摘      要：This paper demonstrated the generation of multi-wavelength bound state noise-like pulse (BNLP) in a dispersion-managed composite-filtered fiber laser consisting of Nonlinear Polarization Rotation (NPR) and Loop. In the case of BNLP， the generation is caused by the interaction between two noise-like pulses (NLPs )induced by the comb-filtering effect， and Bound state level can be artificially controlled in the researches. Our work provides a new method for generating low-coherence pulses and establishes a research idea for the study of the comb-filtering effects.
