Abstract
A fiber, such as a photonic bandgap fiber, is provided, the fiber including a core and a cladding. The core can extend longitudinally and can have a gain medium configured to provide laser amplification to laser radiation propagating along the core. For example, the gain medium may include a dopant configured to provide amplification, when activated by one or more modes of excitation radiation, of laser radiation propagating along said core. The cladding can be radially exterior to the core, and can be configured to provide a low-loss propagation the one or more modes of excitation radiation and a lossy propagation of all modes of laser radiation along the core, the lossy propagation higher than the low-loss propagation, in particular when the one or more modes of excitation radiation is substantially absent from the core. Associated methods and apparatuses are also provided.
