FIG. 1.

Timing of the incident THz pulses, E 1 and E 2, and the probe in the two-dimensional time-domain THz spectroscopy.

FIG. 2.

Two-dimensional profiles of second-order signals for a system with an anharmonic potential and nonlinear damping. (a) Second-order polarization for an anharmonic potential, which corresponds to the response function for the fifth-order Raman scattering with an anharmonic potential. (b) Second-order THz field for an anharmonic potential. (c) Second-order THz field for nonlinear damping. Each image is normalized to its maximum magnitude.

Second-order two-dimensional signals for systems with nonlinear coupling. (a) Second-order polarization for nonlinear coupling, which corresponds to the response function for the fifth-order Raman scattering with nonlinear coupling. (b) Second-order THz field for the nonlinear coupling case. Each image is normalized to its maximum magnitude.
