This is the second of two papers demonstrating that photons with orbital angular momentum can be created in optical waves propagating through distributed turbulence. In the companion paper, it is shown that propagation through atmospheric turbulence can create non-trivial angular momentum. Here, we extend the result and demonstrate that this momentum is, at least in part, orbital angular momentum. Specifically, we demonstrate that branch points (in the language of the adaptive optic community) indicate the presence of photons with non-zero OAM. Furthermore, the conditions required to create photons with non-zero orbital angular momentum are ubiquitous. The repercussions of this statement are wide ranging and these are cursorily enumerated.
这是两篇论文中的第二篇，论证了具有轨道角动量的光子可以在通过分布湍流传播的光波中产生。在 companion paper 中，表明通过大气湍流传播可以产生非平凡角动量。在此，我们扩展该结果并证明这种动量至少部分是轨道角动量。具体而言，我们证明分支点（用自适应光学领域的术语来说）表明存在具有非零轨道角动量的光子。此外，产生具有非零轨道角动量光子所需的条件很普遍。该陈述的影响广泛，在此简要列举。
