Line Plot from Scientific Research

PSD of the THz pulse’s electric field between -3 ps and 3 ps (light blue) and of the residual electric field oscillation from 3 ps to 20 ps (dark blue) measured by electro-optic sampling (see Extended Data Fig. 1 for time trace). PSDs are normalized to the THz pulse’s spectral density at 0.55 THz.
