Based on the inversion characteristic of the truncated Airy pulse in linear regime with third-order dispersion (TOD), we discuss the related dynamics of the truncated Airy pulse in a nonlinear femtosecond optical system. The influence of the initial total power and the Airy pulse width on the nonlinear effect is studied in detail. The results show that when the initial total power is less than one kilowatt, the inversion characteristics of the truncated Airy pulse with several femtosecond width can be observed, and increasing TOD coefficient will lead to tight-focusing of the truncated Airy pulse near the reversed distance. The interaction between the truncated Airy pulses is also studied. These properties are useful for manipulating pulse propagation in fiber system.

基于具有三阶色散（TOD）的线性状态下的截断的艾里脉冲的反演特性，我们讨论了非线性飞秒光学系统中截断的艾里脉冲的相关动力学。详细研究了初始总功率和艾里脉冲宽度对非线性效应的影响。结果表明，当初始总功率小于一千瓦时，可以观察到具有几个飞秒宽度的截断的艾里脉冲的反转特性，并且增加的TOD系数将导致截短的艾里脉冲在反向距离附近紧密聚焦。 。还研究了截短的艾里脉冲之间的相互作用。这些特性对于控制光纤系统中的脉冲传播非常有用。
