Numerical simulation of femtosecond pulses measurement with SPIDER

The object is to measure the amplitude and phase of femtosecond pulses,based on the spectral phase interferometry for direct electric-field reconstruction(SPIDER) of the numerical analysis methods.The spectral phases and intensity of the typical femtosecond pulses were numerical calculated,the spectral phases of these pulses are reconstructed.The reconstructed spectral phases are basically in agreement with the original ones.
