In this study, we developed the flat top laser illumination system by using two axicon lens. As a results, there are some problems that are the geometry between the two axicon lenses. The profile of optical intensity was influenced by the relative position and angle of the two lenses. In the accuracy of the current parts of photonics, it is hard to construct the stable system. And the optical profile of laser itself affected the profile of flat top laser. It is necessary to design more easy and stable the optical system.

在本研究中，我们使用两个轴锥透镜开发了平顶激光照明系统。因此，两个轴锥透镜之间的几何形状存在一些问题。光强度分布受到两个透镜的相对位置和角度的影响。以目前光子学部分的精度，很难构建稳定的系统。而激光器本身的光学轮廓影响了平顶激光器的轮廓。有必要设计更加简单、稳定的光学系统。
