利用脉冲宽度为10 ns、能量为1 J/pulse的Nd：YAG激光辐照铝箔靶，对激光-铝箔相互作用的正向激光等离子体加速过程进行了等离子体诊断的基础研究。电子温度和密度的时间演变进行了评估与静电探针和光谱诊断。从该结果可知，离子的前进方向的平均速度约为40 km/s。此外，等离子体的温度和密度分别约为2.5 - 8 eV和1010cm − 3。
Fundamental investigations of plasma diagnostics of a forward laser plasma acceleration employing laser–foil interactions were conducted for an Al-foil target irradiated with an Nd:YAG laser of 1 J/pulse with pulse width of 10 ns. Temporal evolutions of electron temperatures and densities were evaluated with electrostatic probes and spectroscopic diagnostics. From the results, it was shown that an average speed of ions in a forward direction was about 40 km/s. Also, it was shown that the plasma temperature and density were about 2.5–8 eV and 1010cm−3, respectively.
