Zusammenfassung: | According to the method for generating the wide-spectrum ultra-strong electromagnetic pulse through the action of the laser and the gold wire target, through the interaction of the picosecond laser and the gold wire target, the gold wire target absorbs the energy of the picosecond laser to generate plasma expansion, meanwhile, a large number of electrons overcome potential barriers to escape outwards and oscillate in the laser propagation direction, and the pulse is generated. Therefore, a wide-spectrum ultra-strong electromagnetic pulse signal electromagnetic pulse is obtained; compared with a traditional electromagnetic pulse generation method, the electromagnetic pulse signal intensity generated by the method can reach hundreds of kV/m, the energy conversion efficiency is high, the electromagnetic pulse frequency is distributed between 0 GHz and 2.5 GHz, and the method can be applied to various fields of ultrafast optics, plasma physics, laser plasma accelerators and the like.
