CW and pulse laser light beams are focused at a point in the glass. The pluses induce plasma which grows with the CW light. Video clips available.

The conditions required for a fiber fuse initiation in standard single-mode fibers were determined quantitatively. Systematic investigation on the energy flow balance between these energy sources revealed that the initiation process consists of two steps; the generation of a precursor at the heated spot and the transition to a stable fiber fuse. The latter step needs a certain degree of heat accumulation at the core where waveguide deformation is ongoing competitively. This method is useful for comparing the tolerance to fiber fuse initiation among various fibers with a fixed energy amount that was not noticed before.
