摘要：

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 componentB z and the azimuthal one B θ 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.
