1 Fig. 3 THz pulse-pump optical reflectivity probe spectroscopy on Nd2CuO4.
THz pulse-pump optical reflectivity probe spectroscopy on Nd2CuO4. (A) A schematic of the experimental setup. The probe pulse is changed from visible (Vis) to infrared (IR) region. (B) A typical electric field waveform ETHz(td) of a THz pulse used as an excitation. (C) Fourier power spectrum of the THz pulse shown in (B) and the polarized absorption spectrum of Nd2CuO4 along the a axis. (D) Time evolutions of reflectivity changes ΔR(td)/R by the THz electric field shown in (B) at 0.95, 1.55, and 1.70 eV. Blue solid lines represent normalized waveforms of [ETHz(td)]2. (E) Polarized reflectivity (R) spectrum along the a axis and the spectrum of the reflectivity change at the time origin, ΔR(0)/R. The inset shows the structure of CuO unit forming the 2D CuO plane.
