| 摘 要： | 分别使用两种不同底角的轴棱锥产生无衍射贝塞尔光束。理论分析了单束贝塞尔光及两束贝塞尔光相干叠加后光场的光强分布，分析了产生的局域空心光束在一个完整周期内的特性。数值模拟了光沿纵向传播时光场的横向光强分布，并给出了相关的实验。对单束贝塞尔光及两束贝塞尔光干涉后的中心光斑的大小进行了测量，测量结果与理论计算结果吻合。

| Abstract: | The diffraction-free Bessel beams were generated using two different base angle axicons. The optical intensity distribution in a single Bessel beam and two Bessel beams interference were analyzed, and the characteristics of the generated bottle beams in a complete period were also analyzed. The transverse optical intensity distribution of the beam along the propagation distance was simulated numerically and the related experiments were given. The central spot size of a single Bessel beam and two Bessel beams interference were measured and the results were coincident with the theoretical analysis. |
