【摘要】 径向偏振光是近些年引起广泛关注的一种新型偏振光,它在粒子操控、金属切割和提高显微镜分辨率方面具有广阔的应用前景。径向偏振光可以通过在激光器谐振腔内应用径向偏振光栅反射镜来获得。首先在顶层刻蚀光栅反射镜的模型上通过自编程序分析光栅反射镜各参数对光栅性能的影响,然后设计出光栅反射镜复合结构并结合微纳加工工艺进行了可行性分析。更多还原

【Abstract】 Radially polarized light has been a focus in recent years with wide application in particle manipulation,metal cutting and improvement of microscope resolution.It can be generated by an intro-cavity grating mirror in the resonator of a laser.In this article,the influence of grating’s properties on the parameters was analyzed by aprogram which was written by ourselves in the top-etching grating model.And a suitable grating mirror composite structure was designed with considering of the gratings process feasibility.更多还原
