We investigate the orbital angular momentum of partially coherent beams which are constructed by a superposition of mutually incoherent vortex modes, each mode having a different beam width and topological charge. It is shown that these simple beams nevertheless provide great flexibility in controlling orbital angular momentum through adjustment of the beam parameters and have significant potential for particle rotation and trapping.
我们研究了由相互非相干涡旋模式叠加构成的部分相干光束的轨道角动量，每个模式具有不同的光束宽度和拓扑电荷。结果表明，这些简单光束通过调整光束参数在控制轨道角动量方面仍具有很大的灵活性，并且在粒子旋转和捕获方面具有巨大潜力。
