1. A method for fabricating a second generation high-temperature superconductor (2G-HTS) tape, comprising:
(S1) depositing a first superconducting film on a surface of a ductile metal substrate, wherein the ductile metal substrate is provided with a buffer layer;
(S2) forming a micro-holes array pattern on a surface of the first superconducting film by etching using a reel-to-reel dynamic femtosecond infrared laser etching system, wherein the micro-holes array pattern covers the first superconducting film;
(S3) depositing a second superconducting film on the surface of the first superconducting film, wherein a thickness of the second superconducting film is larger than that of the first superconducting film; and
(S4) depositing a silver protective layer and a copper stabilization layer on a surface of the second superconducting film to fabricate the 2G-HTS tape.
