Genetic algorithm for optimization design of diffractive optical elements in laser beam shaping

Abstract

We address a genetic algorithm (Gas) to achieve optimization design for diffractive optical elements (DOEs) for the laser beam shaping. A laser beam shaping system is investigated using genetic algorithm, in which an incident Gaussian profile laser beam is converted into a zero-order Bessel beam. This algorithm exploits the global nature of the genetic algorithms. High-quality DOEs can be achieved by use of the optimization procedure we proposed.
