Abstract

Gain factor and output performance of erbium-praseodymium codoped ZBLAN double-clad fiber lasers at 2.7 μm with different pumping designs were calculated and analyzed. Single-end backward pumping with a highly reflective mirror butted against one fiber end and dual-end pumping with Fresnel reflections from both fiber ends were found to be the most efficient pumping designs. Ten-watt-level Er/Pr:ZBLAN fiber lasers proved to be achievable with recent diode laser and ZBLAN fiber technologies. Their corresponding optimum fiber lengths for different pumping configurations were determined. It was also found that fiber lasers with a flat evolution of gain factor can obtain the largest output power. Experimental results of 4 m and 12 m fiber lasers showed very good agreement with simulation results.
