超短光脉冲在均匀等离子体中群速度的理论分析
An Integral Method for Analysing Group Velocity of Ultroshort Laser Pulses in a Plasma
摘要
由稀薄均匀的等离子体中麦克斯韦方程的一个严格的积分解求得了超短光脉冲在其中的演化及群速度表达式。结果表明,零级近似下的群速度与近轴近似解相同;一级近似下,群速度与脉宽、空间坐标和时间坐标均有关。
Abstract
An integral solution of Maxwell equation which can discribe the evolution of an arbitrary laser pulse in a homogeneous plasma is given. Especially, an analytical expression of group velocity of ultroshort laser pulses is gotten by using the integral solution. The relativistic effect is neglected in this study.
