摘要 为提高粒子操控的灵活性和精度,一种基于拉盖尔-高斯光束的可控螺旋干涉模式被提出。通过理论分析两束拉盖尔-高斯光束同轴叠加光场,给出了不同参数的变化对干涉光场强度分布的影响。通过仿真模拟,研究参数变化对场强结构的调控作用。结果表明,通过改变两束拉盖尔-高斯光束的拓扑电荷数可以实现干涉模式光场强度极大值的数量和分布的动态调整,增加了对粒子操控的灵活性和可控性,为提高光束微粒操控的精度的提升提供了可能。 In order to improve the flexibility and accuracy of particle manipulation, a controllable spiral Laguerre Gauss beam interference model is proposed. On the basis of theoretical analysis of two Laguerre Gaussian beams, the influence of different parameters on the intensity distribution of interference light field is given. By means of simulation, the concrete effect of parameter variation on the light field intensity has been shown. Results show that dynamic adjustment of the light field intensity interference patterns and the maximum value can be carried out by changing the topological charge number of two Laguerre Gaussian beams. The increase of flexibility and maneuverability in particle control may supply an additional method for the improvement of the beam particle manipulation accuracy.
