We have designed an optimum holographic optical element (HOE) lens recorded by visible laser beams for an infrared two-dimensional vertical-cavity surface-emitting laser (VCSEL) array. The hologram computer-aided design tool that we have developed is used for the optimum design. The optimum HOE has both high light efficiency and a small amount of aberration. An Nd:YAG laser operated at 532 nm and an 8 x 8 VCSEL array operated at 850 nm are used for HOE recording and reconstruction, respectively. The designed lens is experimentally demonstrated, and the experimental results of the lens almost agree with the numerical results.
我们设计了一种由可见激光束记录的用于红外二维垂直腔面发射激光器（VCSEL）阵列的最佳全息光学元件（HOE）透镜。我们开发的全息图计算机辅助设计工具用于优化设计。该最佳HOE具有高光效率和少量像差。分别使用波长为532 nm的Nd:YAG激光器和波长为850 nm的8×8 VCSEL阵列进行HOE记录和重建。对设计的透镜进行了实验验证，透镜的实验结果与数值结果基本一致。
