摘要

通过时域有限差分法,研究了单粒子散射对拉盖尔-高斯(LG)光束轨道角动量态传输的影响,分别研究了散射粒径、粒子位置、椭球粒子半径比、倾斜角度及LG光束初始轨道角动量模式对轨道角动量态衰减的影响。研究结果表明:散射粒子半径越大,轨道角动量态的衰减越严重;散射粒子与光束相对位置的变化,也会引起能量占比的规律变化;初始轨道角动量模式、椭球粒子半径比和倾斜角度对轨道角动量态的衰减均有不同程度的影响。

Abstract

The influence of single-particle scattering on the state transmission of orbital angular momentum (OAM) of Laguerre-Gaussian (LG) beams is studied by using the finite-difference time-domain method. The effects of particle size, particle position, ellipsoidal-particle-radii ratio, orientation angle and initial OAM mode of LG beams on the state degradation of OAM are investigated, respectively. The research results show that the larger the particle radius is, the more serious the OAM state degradation is. The change of the relative position between the scattering particles and the beam also leads to the regular change of the energy proportion. The initial OAM mode, ellipsoidal-particle-radii ratio and orientation angle all have influences on the state degradation at different extents.
