Abstract
An optical fiber includes a doped core doped with thulium and a doped cladding surrounding the doped core. The doped cladding is doped with a second dopant. The doped cladding has a thickness between about 45 μm-650 μm. The doped core and the doped cladding establish a numerical aperture within a range of about 0.04-0.20.
