Influences of SPM on compressed pulse with amplitude modulations and phase perturbations

Self phase modulation (SPM) plays an important role on the compressed pulse in chirped pulse amplification lasers systems. The influences of the SPM with amplitude modulations and phase perturbations on the compressed pulse is simulated. 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.
