Resumo
Optical imaging of spatial distribution of intensity in the focal spot of the terahertz pulse was developed. The technique is based on the THz electric field-induced second harmonic generation in the nonlinear centrosymmetric crystal (SrTiO3). The measurements of the spatial distribution of focal spot of terahertz radiation with the electric field strength over 1 MV/cm were conducted.
