In the paper published by the State Key Laboratory of Strong Field Laser Physics, Shanghai Institute of Optics and Fine Mechanics, Chinese Academy of Sciences in the international academic journal "Physical Review Letters" published on September 11, [Phys. Rev. Lett. 109,115002 (2012)], For the first time, a controlled quasi-single-energy electron beam emission and its deflection effect to the normal direction of the target surface generated by a solid-field plasma wave driven by an ultrafast laser in a strong field are reported. The author of the thesis first proposed a two-step model of laser-driven surface plasma wave phase-locked electron emission, which revealed a new physical mechanism of laser-driven solid surface plasma wave emission quasi-single-energy electron beams, for the future realization of laser manipulation of surface plasma wave electrons Launching to obtain attosecond electron beam pulses provides a new way. Due to the potential applications in ultrafast electron diffraction, laser fusion and fast ignition, the use of ultra-strong ultrashort lasers and solid surface plasma interaction to generate superthermal electron emission has received extensive attention and research. However, most of the experimental results reported so far show that the super-hot electrons mainly exhibit a cone-shaped emission with a large divergence angle between the target surface and the normal, and due to the interaction between the laser and the solid target The high dependence of contrast and plasma scale length, the physical mechanism that affects the electron emission characteristics remains to be explored. Shanghai Optomechanical Co., Ltd. used a high-contrast, medium-intensity (~ 1017Wcm-2) ultrashort pulse laser to irradiate aluminum targets, and for the first time observed a controlled quasi-single energy electron beam emission and its deflection effect. Experiments have found that the electron beam is emitted off the normal direction of the target surface near the laser reflection direction, and is accompanied by an electron evacuation structure at the mirror position relative to the laser reflection direction. By changing the laser parameters, you can manipulate the emission characteristics of the electron beam, such as the energy of the electron beam, the emission angle, and so on. The author of the thesis first proposed a two-step model of laser-driven surface plasmon phase-locked electron emission, and revealed the physical mechanism of quasi-single-energy electron beam emission and its deflection effect: a solid field target irradiated by a strong field ultrafast laser along the target surface Propagating the surface plasmon wave and establishing an interference laser field consisting of incident and reflected laser light. A small number of electrons at the peak of the plasma wave escape from the surface plasmon wave along the direction of laser reflection with a specific phase window due to the higher energy. Interfere with the laser field, and then deflect in the normal direction under the action of qualitative power in the laser field. The theoretical model predicts that the periodic electron emission of surface plasmon waves may produce a quasi-single-energy attosecond electron beam pulse chain.
