The formation of void-free segments is discussed on the basis of examinations of corresponding damage sites and in comparison with known periodic void formation. As an optical discharge pumped at near the propagation threshold power loses its energy, it frequently emits a light pulse instead of forming periodic voids. A similar mode was found just before a stable optical discharge appeared during fiber fuse ignition. This transient mode conversion is the origin of the previously reported irregular void patterns.

Once initiated, opical discharge runs along the fiber core region to the light source and leaves periodic voids whose shape looks like a bullet pointing the direction of laser beam. The relation between damage pattern and propagation mode of optical discharge is still unclear even after the first in situ observation three years ago. Fiber fuse propagation over hetero-core splice point (Corning SMF-28e and HI 1060) was observed in situ. Sequential photographs obtained at intervals of 2.78 us recorded a periodic emission at the tail of an optical discharge pumped by 1070 nm and 9 W light. The signal stopped when the discharge ran over the splice point. The corresponding damage pattern left in the fiber core region included a segment free of periodicity. The spatial modulation pattern of the light emission agreed with the void train formed over the hetero-core splice point. Some segments included a bullet-shaped void pointing in the opposite direction to the laser beam propagation although the sequential photographs did not reveal any directional change in the optical discharge propagation.

From a macroscopic viewpoint, the dissipative soliton concept and an analogy with grassfire help us understand this strange phenomenon. The strong heat-induced absorption of silica glass and the highly confined supply of laser energy cause captured plasma to shift to the light source along the fiber leaving catastrophic damage behind it. From a microscopic viewpoint, the periodic void formation process was unveiled by the statistical analysis of void shapes and ultra-fast videography. The bullet-like shape of the damage train results from the formation of an intrinsic bridge inside the hollow silica melt behind the traveling plasma and the successive compression of detached voids under a steep temperature gradient along the fiber."

Most of our senior colleagues have told us that to experience such opportunities we should maintain a steady interest in our goals and undertake experiments with our own hands. In this paper, the author presents another viewpoint. Always write and present your work with a view to inspiring others to react. Some of the resulting reactions may provide you with unexpected opportunities. This idea is derived from a three-way classification of the unexpected chances that occurred during my fiber fuse research including my self-archiving activity that led to unexpected responses via the Internet.
