Surface Terahertz and Second-Harmonic Generation in Nonlinear Dielectric Crystals via Double Pulse Excitation: Experiments and Modelling
We model THz generation via optical rectification and second-harmonic generation in a double-pulse reflection scheme, capturing dispersion and nonlinear susceptibility effects. The model agrees well with experiments, though deviations suggest two-photon absorption influences the signals.
