The influences of the SPM with amplitudemodulations and phase perturbations on the compressed pulse is simulated.
结果表明：啁啾光脉冲的振幅调制深度和相位扰动深度越大，则压缩后的光脉冲对比度越小；

Furthermore, the effect of aperture parameters on the diffraction characteristics of laser beams with amplitudemodulations is also analyzed.
另外讨论了锯齿光阑参数对有振幅调制光束衍射特性的影响。

The simulations show that more amplitudemodulations and phase perturbations lead to lower contrast of the compressed pulse, and bigger modulation cycle results in wider pre-pulse width.
