Abstract Bi-Sr-Ca-Cu-O superconducting fibers have been successfully prepared by means of the laser-heated pedestal growth method. The superconductivity of the fiber sample is closely related to the composition of source material, the power of focused laser beams, the pull rate of growing fiber, and the condition of post-annealing. The typical size of samples is 150μm x30mm. The onset of transition was 118K, and zero resistance was 85K. The majority phase in the fibers is the 85K (2-2-1-2) phase of the Bi-Sr-Ca-Cu-O materials. Samples are stable and reproduceable.
