用二维半粒子模拟程序模拟研究了超强激光束与过稠密等离子体的相互作用过程 ,发现存在有质动力加速电子及由该电子再拉动离子而产生的等离子体密度通道 ,也发现由高能电子流产生的高强度自生磁场。模拟研究了三种空间形状的激光对钻孔的影响 ,发现激光场径向梯度越大 ,钻孔速度越大 ,越有利于钻孔 ;对反射波进行诊断 ,发现了奇次谐波和偶次谐波。 A two-dimensional half-particle simulation program was used to simulate the interaction between the super-intense laser beam and the over-dense plasma. It was found that there was a mass-momentum accelerating electron and a plasma density channel generated by the electron re-pulling ions. High-strength spontaneous magnetic field generated by electron flow. The effects of three kinds of space shape laser on the drilling are simulated. It is found that the larger the radial gradient of the laser field, the larger the drilling speed is, the better the drilling is. The reflected wave is diagnosed and odd harmonics and even Subharmonic.
