Optical Saturation Produces Spurious Evidence for Photoinduced Superconductivity in

JS Dodge, L Lopez, DG Sahota - Physical Review Letters, 2023 - APS
We discuss a systematic error in time-resolved optical conductivity measurements that
becomes important at high pump intensities. We show that common optical nonlinearities …

Tracing the dynamics of superconducting order via transient third harmonic generation
