Abstract: We employ the genetic algorithm to design a binary optical element system which transforms the Gaussian beam into the uniform circular ring beam. The transformation system is composed of two binary optical elements with 8 phase levels which are placed coaxially. The numerical results indicate that the transformed wavefront has a near-desired waveform and high energy transformed efficiency $tau $EQ 87.3%. The genetic algorithm is better that the other usually used algorithms such as input-output iterative algorithm and stationary phase algorithm. The comparison with the three algorithms are shown in this paper, too.!5
