    • A double-clad optical fiber includes a core, an inner cladding and an outer cladding of silica-based glass. The core may have a radius of less than about 5µmn, a first index of refraction n1 and does not contain any active rare-earth dopants. The inner cladding may surround the core and includes a radial thickness of at least about 25 µm, a numerical aperture of at least about 0.25, and a second index of refraction n2 such that n21. The relative refractive index percent (?%) of the core relative to the inner cladding may be greater than about 0.1%. The outer cladding may surround the inner cladding and include a radial thickness from about 10 µm to about 50 µm and a third index of refraction n3 such that n32. The relative refractive index percent (%) of the inner cladding relative to the outer cladding may be greater than about 1.5%.
    • 双包层光纤包括芯,内包层和二氧化硅基玻璃的外包层。 芯可以具有小于约5μm的半径,第一折射率n1并且不包含任何活性稀土掺杂剂。 内包层可以围绕芯,并且包括至少约25μm的径向厚度,至少约0.25的数值孔径和第二折射率n2,使得n21。 芯相对于内包层的相对折射率百分比(Δ%)可以大于约0.1%。 外包层可以包围内包层,并且包括约10μm至约50μm的径向厚度和第三折射率n3,使得n32。 内包层相对于外包层的相对折射率百分比(%)可以大于约1.5%。
