Abstract:
1. An optical fiber laser structure comprising: a core element having a first end and a second end and comprising a matrix material having an energy migration component and an active gain component for lasing; and a cladding element at least partially surrounding said core element having a length defined between said first end and said second end of said core element, said cladding element comprising a matrix material and an energy migration component identical to that of the core, that absorbs and stores energy from a pumping source and that enables said energy to migrate from said energy migration component in said cladding element to said active gain component in said core element such that said active gain component lases, said energy migration component present in said cladding element in an amount of from 5 to 50 parts by weight based on 100 parts by weight of said cladding element.
