摘要： A light-amplifying fiber arrangement including a pump fiber including glass and a bridge element. At least a portion of a side of the bridge element has been fused to at least a portion of a side of the pump fiber. An active fiber includes a light-amplifying core and a first cladding. The first cladding includes glass. At least a portion of a side of the active element has been fused to at least a portion of a side of the bridge element. A second cladding surrounds the pump and active fibers in order to confine pump light to the fibers. The second cladding includes glass. The arrangement allows coupling of high power levels into the pump fiber, wherein splicing of pigtails to the arrangement is easier than e.g. in case of conventional doubly clad fibers.
