The nonlinear effects on chirped-pulse amplification and recompression are modeled for different levels of amplifier saturation. It is shown that gain saturation and self-phase modulation act together to significantly distort the recompressed pulse after amplification, and a large linear chirp of input pulse contributes to suppress the pedestal of recompressed pulse induced by self-phase modulation in gain saturation regime. Spectral distortion due to gain saturation also has a stronger effect on the low intensity pedestal of recompressed pulse.
