Reconstruction of source-field distribution of a diode bar laser beam by simulated annealing

A method for the simulation and optimization of the source-field distribution of a diode bar laser (DBL) beam by using the stimulated annealing and experimental data in the far field is proposed and illustrated by an example of a DBL JOLD-60-CPNN-1L, showing the applicability of the method. As compared with the previous models, this method is not restricted to the type of diode lasers (DLs), and the reconstructed results are accurate so long as the experimental data are sufficiently accurate.
