Abstract

Summary form only given. Frequency-resolved optical gating (FROG) has gained prominence as a technique for characterizing ultrashort pulses. FROG consists of a spectrally resolved autocorrelation of the pulse to be measured. We have demonstrated phase reconstruction from FROG using a genetic algorithm. Even though only the most basic evolutionary operators were used, the genetic algorithm returned lower FROG errors on certain types of experimental and theoretical pulses then the standard composite iterative algorithm.
