### Abstract

In order to improve the performance of the $$\hbox {Pr}^{3+}$$ Pr 3 + -doped fiber laser, the optimum fiber length and reflectivity of mirrors, the maximum output power, the lasing threshold, and the slope efficiency are needed to be estimated. In this work, a $$\hbox {Pr}^{3+}$$ Pr 3 + -doped fiber laser is considered with fiber Bragg gratings (FBG) as reflectors and an injected pump power in one side. To do so, the rate and power propagation equations of the $$\hbox {Pr}^{3+}$$ Pr 3 + -doped fiber laser are solved numerically by finite difference method and the boundary conditions are obtained by shooting method in an iterative process. The effect of some structural parameters such as the laser background loss, the pump power, the $$\hbox {Pr}^{3+}$$ Pr 3 + dopant concentration, and the reflectivity coefficient of FBG2 on the performance of laser is studied, and the optimum values for fiber length and reflectivity of FBG2 are obtained.
