We demonstrate complete characterization of a femtosecond laser pulse electric field amplitude and phase using a FROG setup with a thick second harmonic crystal and a photodiode replacing a spectrometer. The scheme we propose is intended for high-repetition-rate pulse trains. It takes advantage of the photodiode high dynamic range and can be implemented in a compact size.
