Abstract

A pulse spectrum provides the amplitude of a Fourier transformed pulse |ε(Ω)I2. It is necessary to determine the relative phases of the spectral components to completely characterize the pulse. Chilla and Martinez1 proposed to cross-correlate (in intensity) each spectral component of the pulse, with a reference spectral component. Such a measurement yields the relative delay of each spectral component, which can be used to determine the phase function φ(Ω) of the pulse Fourier transform.
