Fiber Fuse Effect in Hollow Core Optical Fibers

Fiber fuse effect (FFE) is one of phenomena restricting the high power/intensity/pulse energy laser radiation transport through optical fibers. FFE (alternatively, optical discharge (OD) propagation through fiber core) was initially observed in solid state silica fibers [1], and later in fibers of various materials and constructions, including microstructured fibers. Hollow core fibers developed in recent decades can transport high power laser radiation. However, it was recently discovered that FFE is present in such fibers as well [2].
