| Summary: | 碩士 === 國立高雄第一科技大學 === 光電工程研究所 === 98 === In the stage of Laser processing, its performance is usually been affected by the qualities of beam. The output of beam produced by laser which represent with Gaussian distribution and the processing of Gaussian beam will worsens the process cross section of it. And the defect of component structure is therefore caused. The quality controls of process cross section and beam shaping are apparently must have. This abstract demonstrates the designs of coaxial refraction for Laser beam shaping optical systems and non-image optics simulation software based on methodology of Genetic Algorithm to find out the best fit of Nd: YAG laser 355 nm for spherical lens optical systems within a limit of time frame.
Based on the result of utilizations of Genetic Algorithm methodology from the simulation software, it successfully shows 2 pairs of spherical lens optical systems which exactly fits the Laser beam shaping optical systems with integration of from laser source of Gaussian distribution originally to flat top with uniform distribution spread out, with measurement of uniformity of variability reaching 6.695% and 3.864% respectively which displaying on the surface of receiver. The purpose of this whole article aiming for finding the spherical lens optical systems for Laser beam shaping optical systems by utilizations the Genetic Algorithm methodology and the goal of the study research and experiment can be succeed without using the aspherical lens.
