摘要
在高斯光束整形为平顶光束的理论基础上,通过数值模拟,具体分析几个特性参数对两个凸非球面镜的子午截面曲线的影响,根据ZEMAX等光学软件对非球面镜子午截面曲线表达式输入要求,拟合得到误差尽可能小的双凸非球面镜系统结构。
The system composed of two aspheric mirrors is able to convert a Gaussian beam to a flattop beam because of its concise structure,compactness,and sound effects in beam reshaping.And in actual production processing,the asphericity and surface roughness of aspheric mirror are the crucial factors.On the basis of reshaping theory on converting a Gaussian to a flattop,by virtue of numerical simulation,we have calculated and analyzed the several characteristical parameters influence on the design of aspheric mirror surface.Then,according to the actual requirements of input expressions in ZEMAX,we get the best structure of aspheric mirror system by mathematical simulation.
