| 摘 要： | 应用一维粒子模拟方法（Ｐａｒｔｉｃｌｅ－ｉｎ－Ｃｅｌ）数值研究了超短超强激光（Ｉλ２＞１０１８Ｗμｍ２／ｃｍ２）和稀薄等离子体相互作用后等离子体尾波的产生及其对电子的加速。结果表明，单束激光和拍波与稀薄等离子体相互作用后，在等离子体中都能激发起尾波，但拍波激发的等离子体尾波的强度和波长较大，同时等离子体中的电子动量也给加速得比较大

| Abstract: | The excitation of plasma wake wave and acceleration of electrons after interaction between a high intensity ultrashort laser and underdense plasma using a particle in cell simulation is numerically studied. The results show that wake waves can be excited after the interaction between the single frequency or beat wave laser and underdense plasma, but the wake wave has larger strength and longer wavelength, then it can more efficiently accelerate electrons. |
