Light-matter interaction is not only used to melt electronic orders, but also carry the potential as a non-thermal tuning knob to enhance emergent orders. Here the authors demonstrate a light-induced transient enhancement of superconductivity in an iron chalcogenide superconductor via terahertz optical conductivity and terahertz third-harmonic generation by the injection of photo-carriers.
