We demonstrate a single-core multiply doped fiber that, when pumped with a single pump source of 800 nm , emits a more than two-octaves-spanning fluorescence spectrum ranging from 365 to 2300 nm . The fiber preform is manufactured from granulated oxides, and the core is doped with five different rare earths. At a pump power of 250 mW the total emitted power is 34 μ W ; given a core diameter of 6.5 μ m and a numerical aperture of 0.1, the radiance exceeds 3 kW sr 1 cm 2 . We also demonstrate direct diode pumping of the fiber.
