Optical spectra and pump-probe reflection setup on CuO2 planes in Nd2CuO4. a The reflectivity (R, blue) and optical conductivity (σ, red) spectra measured on the ab plane. Electric fields of lights are polarized parallel to a or b axis. The black line in the lower part shows a spectrum of a 7-fs pulse used in the pump-probe (PP) experiments. b A schematic of PP experiments. c A cross-correlation profile of pump and probe pulses corresponding to the time resolution
