We demonstrated a green all-fiber laser by splicing both ends of a 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 mW and 53%, respectively, and the coupled pump power of the two blue GaN pump lasers in the silica fiber core was 652 mW . We estimated that the damage threshold of the spliced structure was at least 21 MW / cm 2 . This splicing technique should be applicable for other wavelengths and glass fibers having low melting temperatures.
