Abstract
We demonstrate a single-core multiply doped fiber that, when pumped with a single pump source of , emits a more than two-octaves-spanning fluorescence spectrum ranging from 365 to . The fiber preform is manufactured from granulated oxides, and the core is doped with five different rare earths. At a pump power of the total emitted power is ; given a core diameter of and a numerical aperture of 0.1, the radiance exceeds . We also demonstrate direct diode pumping of the fiber.
