Abstract
Sum-frequency generation using spectrally asymmetric type II phase matching enables significant simplifications in spectral shearing interferometry as applied for ultrashort optical pulse measurements. We present analytical and numerical models of broadband sum-frequency wave mixing essential to understand the underlying effects. We discuss spectral and temporal limits of the method together with various aspects of experimental implementation: optimization of the retrieval algorithm, calibration procedures, and extension to different spectral regions of particular interest with other crystals.
