Abstract

Generalized simulated annealing (GSA) is introduced as an alternative technique for pulse-retrieval from SHG FROG spectrograms. Successful reconstructions of simulated Gaussian pulses with various phase profiles from 64 x 64 spectrograms were accomplished. This new GSA algorithm was seen to outperform our previous pulse-retrieval routine based on a self-regulating Boltzmann simulated annealing. However, it was noted that the q_v and q_A parameters must be optimized for each problem.
