| Abstract: | 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. |
| Keywords: | Gaussian beam flattop beam convex aspheric mirror parameters of surface shape asphericity |
