Paper Abstract

The use of second harmonic generation as a technique for ultrashort optical pulse width measurement is analyzed in detail to determine the effect of group velocity mismatch between fundamental and second harmonic fields. We find that for interferometric autocorrelation and intensity autocorrelation type II phase matching, GVM has an appreciable effect. While for intensity autocorrelation type I phase matching, the effect is less noticeable.
