摘要

We present a new concept and the experimental realization of a customized spectral shearing interferometry for direct electric-field reconstruction (SPIDER) that is capable of measuring complex broadband laser pulses. The combination of an adapted broadband non-collinear phase matching geometry and the implementation of a home-built Fourier spectrometer enabled characterization of amplitude and phase of highly structured supercontinua with a bandwidth of more than 200 THz at pulse energies of less than 0.2 nJ.
