In order to meet the beam homogenization application requirements of laser diodes, a beam homogenization shaping system was designed with ZEMAX optical design software. A collimation system composed of aspheric lenses and inverted cylindrical lenses telescope system was used to get a circular Gaussian beam. On the basis of deducing homogenization projection radius of fundamental mode Gaussian beams, the two-aspheric lens homogenization system was optimized with ZEMAX. The whole system can obtain a circular spot with energy uniformity over 96% at a large range. Meanwhile, the beam homogenization of high power optical fiber couple module was realized, which satisfied the needs of high uniformity in applications. This research provides an effective way for the homogenization applications of laser diodes.
