Abstract

Practical feasibility of measuring the train-average parameters of picosecond optical pulses being arranged in highfrequency repetition trains is investigated. For this purpose we consider exploiting the triple auto-correlations, whose Fourier transformations give the bispectrum of a pulse train. The main merit of similar approach consists in the capability of recovering signals and revealing asymmetry of pulse envelopes. The triple auto-correlation can be shaped by a three-beam scanning interferometer with the following one- or two-cascade triple harmonic generation. The efficiencies of these processes depend on the number of cascades and differ in various modern materials. The key features of measuring the train-average parameters of pulses with possible frequency chirp are also discussed.
