Abstract

A pulse compressor utilizing fuzzy control method which automatically optimize the dispersions for arbitrary pulse duration is discussed. The fuzzy control system is designed to receive the frequency-resolved optical gating (FROG) trace as an input. The method determines the measured pulse shape, compares it to the next desired pulse shape, and then determines the relevant geometry of the compressor. When the membership function of the fuzzy control is realized by a neural network, it can be combined with FROG network and the geometry of the compressor can be directly determined from the measured FROG trace. A method to determined the membership function is also discussed.
