A protruding-fiber coated pigtail is a fiber assembly with a ceramic ferrule fitted at the coated end, where the fiber tip protrudes a certain distance beyond the ferrule end face, and bare fiber retained at the other end. Unlike conventional flush fiber/ferrule assembly, the protruding-fiber pigtail effectively avoids coating cracks caused by differences in the thermal expansion coefficients of fiber, adhesive, and ceramic ferrule beneath the same coating plane. Its advantages are more evident in the coupling and transmission of medium- and high-power lasers.

Key Features

Direct polishing of the fiber end face requires no auxiliary adhesive during processing, avoiding laser absorption caused by adhesive residue and effectively reducing fiber burnout. The polished bare-fiber end face is highly clean, with no scratches or pits at the core. Coating only the bare-fiber end face, without any ferrule or adhesive, eliminates coating cracks caused by differences in thermal expansion coefficients between substrates beneath the coating. Avoiding the proximity effects of ferrules and adhesive on the laser chip effectively reduces chip COD and contamination. The coating has low thermal absorption and a high damage threshold, with an optical damage threshold > 200 megawatts per square centimeter (certified by a third party in the United States).
