This paper presents a special adjustment method of the vector vortex optical field and constructs a high-precision vector vortex optical field. By applying the Debye vector diffraction method, the regulation laws of optical fields underlying the control of the topological charge, eccentricity parameter, and beam waist are obtained. The results show that these optical parameters have a serious effect on the optical field characteristics, especially that the adjustment of the topological charge can mainly transform the focus area range of the total and longitudinal fields (FWHM of the focal spot) from ${0.8}\lambda$ to ${3.6}\lambda$. In the transverse field, by adjusting the eccentricity parameter ${B}$, the large spot profile gradually dissipates and is replaced by a newer, smaller central vortex field. The FWHM of the vortex field is about ${0.3}\lambda$ and contains two bright spots, each of which has a minimum size of ${0.12}\lambda {-} {0.13}\lambda$. The beam waist can significantly alter the beam propagation process. In particular, the specific value of the beam waist can cause the focus spot to split. The research in this paper supplements a new method of precise operation for the field of optical micromanipulation and has practical application significance in related fields.

高精度矢量涡旋场的构造

本文提出了一种特殊的矢量涡旋光场调节方法，并构造了一个高精度的矢量涡旋光场。通过应用德拜矢量衍射方法，获得了控制拓扑电荷，偏心率参数和束腰的基础上的光场调节律。结果表明，这些光学参数对光场特性有严重影响，尤其是拓扑电荷的调整主要可以将总场和纵向场的焦点区域范围（焦点的FWHM）从$ {0.8}转换。 \ lambda $到$ {3.6} \ lambda $。在横向场中，通过调整偏心率参数$ {B} $，大的斑点轮廓逐渐消散，并被更新的较小的中心涡流场取代。涡旋场的FWHM约为$ {0.3} \ lambda $，其中包含两个亮点，每个亮点的最小大小为$ {0.12} \ lambda {-} {0.13} \ lambda $。束腰可以显着改变束传播过程。特别是，束腰的特定值可能导致焦点分离。本文的研究为光学显微操作领域的一种新的精确操作方法提供了补充，在相关领域具有实际的应用意义。
