Abstract: Descriptions are given of two methods for measuring the effective duration of ultrashort pulses: One is based on the two-photon efficiency in a semiconductor correlator and the other is based on the reactive effect in second-harmonic generation. These methods were used to study the output parameters of a modelocked laser with ring and linear resonators.
