摘要

本文利用Richards-Wolf矢量衍射积分模型对-2到4阶的贝塞尔型矢量光束经高数值孔径聚焦后焦平面处的光强分布进行了理论仿真和特性研究, 并对矢量光束的聚焦场在真空下俘获玻璃小球的梯度力分布进行了仿真. 结果表明聚焦场的形状、尺度及各分量的变化与矢量光束的阶数有密切关系, 且具有特定的规律; 此外, 聚焦场的梯度力分布与矢量光束的阶数也有密切关系,并且具有多种不同形状和尺度的光陷阱.

The intensity distribution of the -2 to 4-order vector Bessel beams in the focal planes of a high numerical aperture lens are simulated based on the Richards-Wolf's vector diffraction integral model, and the distribution of gradient force capturing a glass ball in vacuum is also simulated. The simulated results show that the patterns, the areas of the focused light field and the variation of components are closely related to the order of the vector beams. Additionally, the distribution of the focused light field gradient force is closely related to the order of the vector beams, which can form optical traps with different shapes and scales.
