“…In the traditional phase retrieval algorithm, phase is extracted from the filtered alternating-current component of the Fourier transform [8]. The filter is set by manual selection and adjustment, and different widths or shapes of filter windows produce different phases [10]. The uncertainty of the reconstructed pulses comes from the uncertainty of the spectral phase.…”

We introduce a technique for the measurement of femtosecond optical pulses. This technique significantly reduces the uncertainty coming from the filter when used in the traditional technique, and an accurate spectral phase is retrieved. With the retrieved phase, the electric field, phase, waveform, as well as the duration of femtosecond optical pulses can be precisely reconstructed. The simulated autocorrelation traces deduced from the reconstructed pulsed electric field are in good agreement with the measured ones. This technique removes the manual procedure of selection and adjustment of the filter, an automatic measurement being realized.

“…The spectral phase retrieval from interferograms with different replicas separations have been analyzed in section 2.4. The analysis and comparison of spectral phase retrieval error with wavelettransform and Fourier transform with different filter widths is simulated and calculated in reference [10].…”

“…The filter is set by manual selection and adjustment. A problem is that different widths or shapes of the filter produce different spectral phases [10]. Thus the uncertainty of the spectral phase contributes to the uncertainty of the reconstructed pulses.…”
