摘要：

We focus on a defect that often occurs in spectral phase interferometry for direct electric-field reconstruction(SPIDER) systems: the features of the measured pulse should be predicted properly so as to adjust suitable parameters for the phase retrieval. This defect actually makes some limitations to the applicability of these systems. Errors occur likely when chirped pulses are to be measured. To prove this, we set up a conventional SPIDER system to measure the femtosecond pulses from a Ti:sapphire laser and the chirped pulses resulted from the broadening of a BK7 glass block. The duration of the chirped pulse is 295 fs, while 322 fs is obtained after spectral shear correction. The latter is closer to theorectically predicted value of 313 fs. The experimental results show that errors do occur when the measured pulse has obvious chirp, yet not enough dispersion is offered by the broadening unit of the SPIDER system. However, this error can be decreased by calibrating the spectral shear by means of recording the spectra of the upconverted pulses.
