| 摘 要： | 针对激光光束的能量均匀化研究，先后出现了多种方法，基于“不等步长采样”原理设计了包含非球面镜的光学系统。首先从理论上分析了其可行性，然后对实际激光光束进行了能量均匀化的设计。模拟分析结果表明，出射光束发散度小于0．02°，照度均匀度达92．9％，证明了此方法的可行性。

| Abstract: | There are many approaches to realize laser energy uniform. This paper presents a new method based on ＂variable step sampling＂ to design a optical system including aspheric lens. A model is built and simulated in ZEMAX and TRACEPRO. The result shows that the energy uniformity of the outgoing beam is 92.9 %, and its divergence is less than 0.02%. |
