000170977 5203_ $$aHigh-temperature textured YBCO superconductors are considered relevant for applications requiring strong flux pinning, and hence enhanced critical current density and resilient levitation forces, such as maglev systems, magnetic resonance imaging and nuclear magnetic resonance magnets. Improving the performance of YBCO for such applications is commonly achieved by enhancing the flux pinning properties through various mechanisms. In addition, either related to the sample fabrication process or demanded by the final operation conditions, machining these highly brittle samples would be desirable for a number of applications and is a challenging demand. This work reports on the use of ultrashort-pulsed laser irradiation to machine holes into top-seeded melt-growth YBCO samples and how this processing affects their microstructure and superconducting behavior. The x-ray diffraction (XRD) and scanning electron microscopy results demonstrate that ultrashort-pulsed laser machining can create well-defined holes with diminishing microstructural damage. The superconducting properties of the laser-machined samples are essentially preserved, even compatible with the enhancement in the critical current density and levitation force properties. These findings demonstrate the potential of ultrashort-pulsed lasers as a viable tool for machining textured YBCO products and enhancing their performance without degrading their functional properties. This method paves the way towards the generation of artificial defects, machining and shaping of high Tc superconductor ceramics into precisely well-defined complex geometries relevant for power applications.
