| Abstract: | In this paper the simulating annealing method is introduced into the optimal design process to improve the long range homogeneity along the line focus. The results show that the unequal width element CLA is able to improve the homogeneity along the focus line for an incident laser with both Gaussian and uniform distribution. The design results are also given. |
