摘要

贝塞尔-高斯光束(BGB)是一种物理上可实现的光束,广泛应用于微操作和光学捕获等领域。在这些应用中,光束形状系数(BSC)的评估变得十分必要。以往的研究表明,在某些情况下,用不同方法得到的 BGB 的光束形状系数存在偏差。本文采用径向正交法计算 BSCs,并与角频谱分解法和有限级数技术计算的 BSCs 进行了比较分析。本文讨论了源自蒸发波的贡献和 BSC 井喷的情况,为相关的 BSC 评估方法提供了深刻的见解。本文为计算 BGB 的 BSC 提供了另一种方法。

Evaluating the beam shape coefficients of Bessel-Gauss beams with radial quadrature: a comparison with angular spectrum decomposition and finite series methods.

The Bessel-Gauss beam (BGB) stands as a physically realizable beam extensively employed in applications such as micromanipulation and optical trapping. In these contexts, the assessment of beam shape coefficients (BSCs) becomes imperative. Previous research reveals that the BSCs of the BGBs obtained with different methods deviate from each other under certain circumstances. In this paper, the formulation of BSCs employs the radial quadrature method, and a comparative analysis is conducted with counterparts formulated using the angular spectrum decomposition and the finite series technique. Contributions stemming from evanescent waves and the situation of the BSC blowing-ups are discussed, offering a deep insight of pertinent BSC evaluation methods. The paper provides an alternative approach for calculating the BSCs of the BGBs.
