Abstract

To enhance the output pulse energy of anomalous-dispersion mode-locked fiber lasers, the energy-managed soliton (EMS) fiber laser has emerged as a promising approach. Nevertheless, systematic optimization strategies for achieving higher-energy single pulses in such systems remain to be thoroughly explored. In this work, we present the first optimized design of a thulium-doped EMS mode-locked fiber laser. By conducting comprehensive numerical simulations of critical laser parameters–including pump power, spectral filter bandwidth, single-mode fiber length, and saturation power of a saturable absorber–we develop a novel design framework that significantly boosts output pulse energy. This approach yields pulses with 66.5 nJ energy, 38.74 kW de-chirped peak power, and 1.5 ps pulse duration. Our findings offer essential theoretical guidance for advancing high-energy pulse generation in anomalous-dispersion mode-locked laser systems.
