Research Abstract

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.
