Abstract
An optically-active air-clad fiber () includes a core () that facilitates doping with an ion optically excitable and having a three-level optical transition when pumped at a first end () of an optical cavity () by a multimode pump source () at a pump wavelength () for lasing at a signal wavelength () different than the pump wavelength () at a second end () of the optical cavity (), the core () having a refractive index, wherein the core () is transformed from the first end to proximate the second end () thereof such that the optically-active fiber () is multimode at the pump wavelength proximate to the first end (), and is single-mode at the signal wavelength proximate to the second end (). An air-clad () surrounds at least one portion of the core () and has a lower effective refractive index than the refractive index of the core ().
