Abstract: We present experimental and simulation results on the dissipative soliton energy quantization effect in the negative dispersion regime of an all-fiber Er-doped ring laser. A fiber filter is inserted into the cavity to facilitate the energy flow out of the cavity under net negative dispersion value conditions, and a single-dissipative soliton operation with the maximum pulse energy of 0.135 nJ is achieved. The dissipative soliton splitting occurred when the pump power is increased by dual-pulse, triple-pulse, and four-pulse operations. Simulations based on the extended nonlinear Schro center dot dinger equation have been performed to confirm the multiple-dissipative soliton generation and soliton energy quantization in a net negative dispersion mode-locked fiber laser. These experimental and simulation results will help to improve the pulse energy in the negative dispersion regime and provide a more unified theory for the understanding of the mode-locking regimes in negative dispersion lasers.
