论文摘要
我们得出表达能量,线性动量和角度动量含量的圆形极化laguerre-gaussian波包,在自由空间中传播。考虑了电磁场的矢量性质,并检查了在拉瓜尔 - 高斯梁的理论处理中通常调用的近似近似的各种后果。
We derive expressions for the energy, linear momentum, and angular momentum content of circularly polarized Laguerre-Gaussian wave-packets propagating in free space. The vectorial nature of the electromagnetic field is taken into account, and the various consequences of paraxial approximation, which is typically invoked in theoretical treatments of the Laguerre-Gaussian beams, are examined.
