We demonstrated a high-power and highly efficient Pr-doped waterproof fluoride glass fiber laser at 522.2nm excited by two-polarization-combined GaN laser diodes and achieved a subwatt output power of 598mW and slope efficiency of 43.0%. This system will enable us to make a vivid laser display, a photocoagulation laser for eye surgery, a color confocal scanning laser microscope, and an effective laser for material processing. Direct visible ultrashort pulse generation is also expected.
