Bound state noise-like pulses generation from composite filtering effects
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.
