摘　　要：应用多光子非线性Compton散射模型,对Compton散射下的三阶色散对超短光孤子脉冲自频移的影响进行了研究,结果表明,Compton散射使三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△δ_T∝T_0^(-7)Z^(5/2)β_3^(4/5),但其斜率α_T不同于散射前的斜率α。Abstract： Using the model of multi-photon nonlinear Compton scattering, influences of the third-order dispersion under Compton scattering on the extra-short optical soliton self-frequency shifting were studied. The results show that the third-order dispersion under Compton scattering has the strong repressive 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 divided into two clearer and higher spectrum crests in the frequency domain. Self-frequency shifting △δT∝T0^-7Z^5/2β3^4/5,but the coupling slope aT and slope a before the scattering are not the same.
