    强飞秒激光脉冲在氮气传输时会受到线性和非线性效应的影响，其中非线性高阶克尔效应颇为重要。基于一个二维轴对称激光传输模型对强飞秒激光在氮气中的传输进行数值模拟，研究了高阶克尔效应各项非线性折射率的变化对激光传输的影响。

    The transmission of an intense femtosecond laser pulse in nitrogen may be influenced by linear and nonlinear ef?fect,in which the higher?order Kerr effect plays an important role. A 2?D axial symmetric laser transmission model was used to carry out numerical simulation for transmission of intense femtosecond laser pulse in nitrogen. The impact of the nonlinear refrac?tive index of higher?order Kerr effect on the femtosecond laser pulse′s transmission in nitrogen is investigated in this paper.
