利用轴棱锥产生的两束贝塞耳光相干实现局域空心光束.基于"相干贝塞耳光产生具有塔尔博特效应的局域空心光束"的理论,数值模拟了两束贝塞耳光干涉后光场沿传输距离变化的光强分布及一个周期内光强的演变和局域空心光束的形成过程.实验中通过两个不同底角的轴棱锥产生两束具有不同径向波矢的贝塞耳光进行相干形成局域空心光束,实验结果与理论分析及数值模拟相吻合.

An experiment study on the bottle beam which are produced by the interfering of the two Bessel beams generated from the axicons is proposed. Based on the "bottle beam with Talbot effect generated by interfering Bessel beam", the three-dimensional optical intensity distribution of the superimposed optical field along the propagation distance and the intensity evolution of the bottle beams in a complete period are simulated numerically. In the experiment, the bottle beam is generated by two interfering Bessel beams with different radial wave vector. Our result fits well with theoretical calculation and numerical simulation.
