(color online) Transient c-axis reflectance of La_1.675Eu_0.2Sr_0.125CuO₄, normalized to the static reflectance. Measurements are taken at 10 K, after excitation with IR pulses at 16 μm wavelength. The appearance of a plasma-like edge at 60 cm⁻¹ suggests a photoinduced superconducting coherence.^[27]
