研究了非相对论性强线偏振和圆偏振激光脉冲在初始均匀低密度等离子体中碰撞主导极限下产生的准静态磁场。利用自洽的解析模型，详细推导了碰撞主导极限下激光脉冲包络中的准静态磁场，得到了磁场的精确解析表达式，并讨论了磁场与激光和等离子体参数的关系.从这种自洽模型出发，同时导出了包含轴向分量B（z）和方位分量B（θ）的准静态磁场方程。讨论了准静态磁场与入射激光强度、激光脉冲横向聚焦半径、电子密度和电子温度的关系。
Quasistatic magnetic fields generated by nonrelativistic intense linearly polarized (LP) and circularly polarized (CP) laser pulses in an initially uniform underdense plasma in the collision-dominated limit are investigated analytically. Using a selfconsistent analytical model, we perform a detailed derivation of quasistatic magnetic fields in the laser pulse envelope in the collision-dominated limit to obtain exact analytical expressions for magnetic fields and discuss the dependence of magnetic fields on laser and plasma parameters. Equations for quasistatic magnetic fields including both axial component B(z) and the azimuthal one B(theta) are derived simultaneously from such a selfconsistent model. The dependence of quasistatic magnetic field on incident laser intensity, transverse focused radius of laser pulse, electron density and electron temperature is discussed.
