Simulation on the dynamic process of dissipative solitons in fiber lasers under multiparameter combinations

Positive dispersion ring cavity ultrafast lasers can obtain dissipative soliton output with higher power density. The process of establishing a stable soliton is affected by complex factors such as dispersion, nonlinearity, loss, gain, and key component parameters. Due to the complexity of the parameters involved, the experimental system cannot guarantee the reproduction of the input elements. This means that the experimental research cannot implement strict variable control. Therefore, establishing a laser simulation model and studying the dynamics of soliton development under complex parameter combinations can help us to conveniently understand the feasibility of the scheme. Through the simulation of complex parameter combinations, it is found that there is a clear optimal working range for obtaining stable mode-locked soliton output, which can be used to guide the design and optimization of laser experiment schemes.
