Abstract
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.
