The bright THz source is essential for exploring nonlinear THz field-matter interac-tion and spectroscopy. Recent advances in high peak-power pulsed THz sources with intensity greater than 1 MV/cm provided unique opportunities to study transient dy-namics of non-perturbative states of matter and to investigate strong light-matter interac-tions. The records of pulsed THz field strength are in the range of 10 to 10 MV/cm from laser-induced gas plasma with two-color laser excitation in dry nitrogen, or up to about 80 MV/cm from organic crystals with the optical rectification. Extremely in-tense sub-cycle pulses pulse at THz/far-IR region will enable strong field-matter inter-action and investigation of a wide range of scientific phenomena.
