The accurate FROG characterization of attosecond pulses from streaking measurements

We describe a new attosecond FROG algorithm optimized for the characterization of sub-100 as pulses from streaked electron spectra. We make improvements upon the treatment of the attosecond streaking spectrogram, and show that these are necessary in order to accurately characterize shorter pulses wi...

Description
Summary:We describe a new attosecond FROG algorithm optimized for the characterization of sub-100 as pulses from streaked electron spectra. We make improvements upon the treatment of the attosecond streaking spectrogram, and show that these are necessary in order to accurately characterize shorter pulses with ever larger bandwidths. We investigate the effects of the approximations that must be made in order to apply the generalized projections scheme.
