Lately, yellow lasers have been showing promising results for the treatment of diabetic retinopathy. In this study, a numerical model for Dy-doped yellow fiber lasers has been developed to analyze the impact of the most significant input parameters. The impact of input pump power, cavity length, and reflectivities of the mirrors on the output signal power has been studied, by evaluating the impact of the lifetime of Dy-energy levels. Additionally, an investigation of excited state absorption has been conducted. Simulation results provide valuable insights into both the qualitative and quantitative influence of these input parameters on the performance and efficiency of Dy-doped fiber lasers for yellow emission.
