摘要

给出了聚焦圆偏振光束角动量的计算方法。计算结果表明，焦点处的角动量随着数值孔径的增大而增大，表明光束和透镜之间存在角动量交换。

Angular momentum in tightly focused beams with circular polarization

Calculations of the angular momentum of focused circularly polarized beams are presented. The calculations indicate that the angular momentum at the focus increases with the numerical aperture, suggesting an exchange of angular momentum between beam and lens.
