A developed method of fringe free spectral phase interferometry reconstruction (FF-SPIDER) for femtosecond pulse measurement is demonstrated with theoretical simulation and experimental measurements. FF-SPIDER overcomes the disadvantages of the traditional SPIDER in which the time delay measured pulse replica results in fringes in the interference spectrum and complicates the spectral phase reconstruction. The measurement results show that FF-SPIDER reconstructs the amplitude and phase of the measured pulses with higher efficiency, higher accurate and lower requirements on measurement apparatus.
