Recently, characteristic optical transverse modes have been used in a variety of optical fields. In this work, we report on coherent quench spectroscopy using optical vortex pulses as a phase destruction of high-Tc superconductivity. The results show a photoinduced localized superconductivity, leading to a new development in photoinduced phase transitions.
