Abstract
Amplitude and phase relative to an interferometrically established phase of ultrashort replica pulses (15) utilizes spectral phase interforemetry for direct electric field reconstruction by frequency shifting chirp replica pulses (16) of an optical pulse to be measured. The replicas of the pulses, relatively delayed in time, are generated by an interferometer (12).
