The high order harmonic emission from thin plasma foils irradiated by two circular polarized, counter propagating laser pulses with their electrical vectors rotating in different direction was investigated via 1\|D particle in cell (PIC) simulations, More than 200 harmonics can be generated with the laser intensity of 10 21 W/cm 2.
通过一维粒子 (particleincell,简称PIC)模拟 ,研究了超薄等离子体薄膜在两列旋转方向相反的圆偏振激光脉冲作用下的高次谐波辐射。
