摘    要:将Fokker-Planck方程转换到电子在激光场中振荡的坐标中,得到了光场作用下的电子动力学方程;给出了圆偏振激光场作用下的电子-离子、电子-电子碰撞项;在不同的场强区域讨论了等离子体热电输运.研究表明,当电子在激光场的颤动速度接近或者大于其热运动速度时,与没有激光场情况相比,等离子体的热电输运减小很多. 关键词

关 键 词:等离子体  激光场  输运  动力学方程

Abstract:The kinetic equation for electron in an intense laser field is derived by transio-rming the Fokker-Planck equation into the local coordinate system of electron oscl-llation in the field. The electron-ion collision in circularly-polarized light is calcu-lated, and the electron-electron collision is discussed. The plasma thermo-electric transports are studied for different intensity regions of the circularly-polarized laser field. It is found that, when the electron quivervelocity in laser field is comparable with its thermal velocity, the thermo-electric transports can be largely decreased as compared to the case without laser field.
