We have demonstrated optical vortex pulse-induced coherent quenching of cuprate high temperature superconductor (Bi2212) to generate a localized superconductivity reflecting a zero-intensity core. In this study, we report on the spatio-temporal evolutions of optical vortex-induced superconductivity by spatially-resolved imaging of Bi2212.
