The contrast of the output femtosecond pulse reduced and the length of the pre-pulse enlarged as the degree of the saturated amplification severed.
随着系统进入增益饱和区,压缩光脉冲的对比度明显降低,预脉冲长度显著增大。

The simulations show that more amplitude modulations and phase perturbations lead to lower contrast of the compressed pulse, and bigger modulation cycle results in wider pre-pulse width.
The old choppy and clunky pre-swing rhythmic feel is still there in the pulse and banjo sound, but this was a new notion of how jazz composition might evolve.
