用频域干涉技术观测到了电子密度微扰的非对称空间分布。泵浦激光脉冲的椭圆形分布增强了外凸体的尾迹幅度。这种不对称性可以用从轴对称线性理论扩展而来的二维分析模型来解释。
The asymmetric spatial distribution of electron density perturbation is observed by using a frequency-domain interferometry technique. The wake amplitude of the outside bump is enhanced by the elliptical distribution of the pump laser pulse. This asymmetry can be explained with a two-dimensional analytical model expanded from cylindrically symmetric linear theory.
