摘要：

应用多光子非线性Compton散射模型，对Compton散射下的3阶色散对超短光孤子脉冲自频移的影响进行了研究，通过理论分析、数值模拟和拟合，结果表明，Compton散射使3阶色散对孤子自频移有较强的抑制作用，在时域中引起孤子脉冲的调制振荡结构更为明显，频域中的频谱被分为两个较清晰的、峰值较高的谱峰，孤子自频移，但其斜率不同于散射前的斜率。

Abstract:

Using the model of the multi-photon nonlinear Compton scattering，theory analysis，numerical simulation and fitting method，we have studied the Influences of the third-order dispersion under Compton scattering on the extra-short optical soliton self-frequency shifting. The results show that the third-order dispersion under Compton scattering can take place the stronger depressant effect on the extra-short optical soliton self-frequency shifting. There is a clearer modulation oscillating system of the soliton pulse in the time domain. The frequency spectrum is taken place two clearer and higher crest value spectrum crests in the frequency domain. There is a between the and ，，，but the coupling slope and before the scattering slope are not same.

Key words: nonlinear optics∣third-order dispersion∣self-frequency shifting∣Fourier transform∣multi-photon nonlinear Compton scattering
