本文研究了高强度高对比度激光脉冲辐照下不同纳米结构目标中的粒子加速度。我们发现，相对于平面目标，纳米结构目标发射粒子的最大能量和方向性显著增强。我们从理论上详细地研究了快电子在纳米线靶中的产生和传播。这种靶具有极高的激光能量到电子动能的转换效率。我们观察到电子束沿着导线引导。理论和仿真结果与实验结果比较吻合。
We have studied particle acceleration in different nanostructured targets irradiated by high intensity laser pulses of high contrast. We find that the maximum energy of emitted particles and their directionality is significantly enhanced in the case of nanostructured targets with respect to plane targets. We have studied theoretically in detail the generation and propagation of fast electrons in nanowire targets. Such targets exhibit an extraordinary high conversion efficiency of laser energy into electron kinetic energy. We observe guiding of electron bunches along the wires. Results from theory and simulation compare reasonably well with the experimental data.
