Abstract

A method for fabricating a second generation high-temperature superconductor (2G-HTS) tape, including: (S1) depositing a superconducting thin film on a surface of a ductile metal substrate with a buffer layer; (S2) forming a micro-holes array pattern on a surface of the superconducting thin film by etching using a reel-to-reel dynamic femtosecond infrared laser etching system, where the micro-holes array pattern covers the superconducting thin film; (S3) depositing a superconducting thick film on the surface of the superconducting thin film; and (S4) depositing a silver protective layer and a copper stabilization layer on a surface of the superconducting thick film.
