Abstract: Dy3+-doped fluoride fiber lasers have important applications such as in environmental monitoring, real-time sensing, and polymer processing. At present, achieving a high-efficiency and high-power Dy3+-doped fluoride fiber laser in the mid-infrared (mid-IR) region over 3 μm is a scientific and technological frontier. Typically, Dy3+-doped fluoride fiber lasers utilize a unidirectional pumping method, which suffers from the drawback of high thermal loading density on the fiber tips, thus limiting power scalability. In this study, a bi-directional in-band pumping scheme, intended to address the limitations of output power scaling and to enhance the efficiency of the Dy3+-doped fluoride fiber laser at 3.2 μm, was investigated numerically based on rate equations and propagation equations. The detailed simulation results reveal that the optical-optical efficiency of the bi-directionally in-band pumped Dy3+-doped fluoride fiber laser can reach 75.1%, approaching the Stokes limit. The potential for further improvement of the efficiency of the Dy3+-doped fluoride fiber laser was also discussed. The bi-directional pumping scheme offers the intrinsic advantage of mitigating the thermal load on the fiber tips, unlike unidirectional pumping, in addition to its high efficiency. As a result, it is expected to significantly scale the power output of Dy3+-doped fluoride fiber lasers in the mid-IR regime.
