On the initiation of fiber fuse damage in high-power ytterbium-doped fiber lasers
文献摘要：
Fiber fuse effect can occur spontaneously and propagate along optical fibers to cause widespread damage;it threatens all applications involving optical fibers.This paper presents two results.First,it establishes that the initiation of fiber fuse(IFF)in silica fibers is caused by virtual-defect-induced absorption.Critical temper-atures and critical optical powers for IFF are simulated for the first time using a 3D solid-state heat transfer model with heat source generated by the virtual-defect-induced absorption.In this method,formation energies of the virtual defects can be uniquely determined,which offers critical information on the chemical reasons for fiber fuse.Second,this paper offers a method to evaluate operating temperatures of fiber lasers.General analytical solutions of the operating temperatures along gain fibers are deduced.Results of 976-nm laser-diode-pumped and 1018-nm tandem-pumped ytterbium-doped fiber(YDF)amplifiers using 10/130-μm YDFs are calculated.Potential limits caused by fiber fuse are discussed.
