一种V型Ince-Gaussian光束空间模式分布特性研究
|
摘要
基于特定参数下的因斯高斯Ince-Gaussian(IG)光束的奇偶模式线性叠加,提出了一种每个光瓣均为"V"字形的光束模式(VIG模式)。通过实验与数值模拟对所提VIG模式进行分析研究,结果发现VIG模式的"V"字形光瓣个数为其阶数的两倍。通过给奇偶模式施加一个初始相位差可以自由调控"V"字形光瓣连续分离为一大一小两个光瓣,并且可以对调两个光瓣的空间位置。通过力场分析发现,VIG模式有望应用于细胞分选。通过两个偶模一个奇模阶数比为1∶3∶2进行叠加,可以生成三个分支的VIG模式。
Based on the linear superposition of the odd and even modes of the Ince-Gaussian(IG)beam,a novel V-shaped IG beam mode is proposed,called as V-shaped Ince-Gaussian mode(VIG mode),in which each light petal has a V-shaped structure.The experimental and numerical simulation results show that the number of V-shaped petals is twice as much as the order of the VIG mode.Given an initial phase difference between the odd and even modes,each V-shaped petal in VIG modes is split into a large and a small light petals.Moreover,this splitting process is freely controlled and the spatial positions of these two separated petals are able to exchange.The analysis of the force field of the VIG mode shows that the VIG mode is expected to be a candidate beam for cell sorting.Further,if the linear superposition is conducted by two even modes and one odd mode with order ratio of 1∶3∶2,a three branches VIG mode can be generated.
