Abstract

An optical fiber comprising a core (120, 220, 320, 420, 520, 620, 720, 820) having at least one rare earth for providing light having a first wavelength responsive to the fiber being pumped by light having a second wavelength that is different than the first wavelength; an inner region (270, 370, 470, 570, 670, 770, 870) disposed about the core; a pump cladding (224, 324, 424, 524, 624, 724, 824) disposed about the inner region; a second cladding (128, 228, 328, 628, 728, 828) disposed about the pump cladding; wherein the index of refraction of the second cladding is less than that of the pump cladding, the index of refraction of the pump cladding is less than that of the inner region, and the index of refraction of the inner region is less than that of the core; and wherein the core comprises a V-number at the first wavelength of greater than 2.405 and wherein the core comprises a numerical aperture of less than 0.12.
