الوصف: The ultrafast manipulation of quantum material has led to many novel and significant discoveries. Among them, the light-induced transient superconductivity in cuprates achieved by melting competing stripe orders represents a highly appealing accomplishment. However, recent investigations have shown that the notion of photoinduced superconductivity remains a topic of controversy, and its elucidation solely through c-axis time-resolved terahertz spectroscopy remains an arduous task. Here, we measure the in-plane and out-of-plane transient terahertz responses simultaneously in a stripe-ordered non-superconducting La$_{1.875}$Ba$_{0.125}$CuO$_4$ after near-infrared excitations. We find that although a pump-induced reflectivity edge appears in the c-axis reflectance spectrum, the in-plane scattering rate of quasiparticles is transiently enhanced without any signature of the formation of superconducting condensate within the CuO$_2$ planes. Therefore, we conclude the out-of-plane transient responses cannot be explained by an equivalent of Josephson tunneling. Our results provide a critical evidence that transient superconductivity cannot be induced by melting the competing stripe orders with pump pulses whose photon energy is much higher than the superconducting gap of cuprates. ; Comment: 10 pages, 4 figures
