We demonstrated a green all-fiber laser by splicing both ends of a ${\mathrm{Pr}}^{3+}$ -doped ZBLAN fiber to silica fibers, whose ends were coated with a dielectric thin film. The output power and the slope efficiency were $322\mathrm{mW}$ and 53%, respectively, and the coupled pump power of the two blue GaN pump lasers in the silica fiber core was $652\mathrm{mW}$ . We estimated that the damage threshold of the spliced structure was at least $21\mathrm{MW}/{\mathrm{cm}}^2$ . This splicing technique should be applicable for other wavelengths and glass fibers having low melting temperatures.
