摘要：

Generation of high energy THz pulses by tilted pulse front excitation is reviewed. The basic idea and the realized setups are described. Properties of THz pulses generated by using different pump lasers are summarized. Nonlinear optical effects induced by the high energy THz pulses were observed, such as nonlinear refraction, self-phase modulation, saturation of THz absorption, and free carrier generation. The main results on these phenomena are described. The possibility of using THz pulses as a quasi-dc field for increasing the cut-off frequency in high harmonic generation is analyzed. The THz generation setup used in recent experiments is analyzed and arrangements for achieving better THz beam quality and higher THz pulse energy are considered. Finally, some results of calculations indicating significantly increased generation efficiency of 0.2-THz pulses compared to generation efficiency of 1-THz pulses are presented.
