We propose a new kind of Bessel beams, namely the segmented-phase high-order Bessel beams (SHBBs). Compared to the traditional high-order Bessel beams, the proposed beams have segmented helical phases instead of the integer topological-charge helical phases. As a result, the phase segments of the beams may carry orbital angular momenta of different topological charges. The simulation and experimental results show that the SHBBs also have the properties of non-diffraction and self-recovery. The proposed beams have potential applications in optical communication and optical manipulation.

分段相位高阶贝塞尔光束

我们提出了一种新型的贝塞尔光束，即分段相高阶贝塞尔光束（SHBBs）。与传统的高阶贝塞尔光束相比，所提出的光束具有分段的螺旋相位，而不是整数的拓扑电荷螺旋相位。结果，光束的相位段可以携带不同拓扑电荷的轨道角动量。仿真和实验结果表明，SHBBs还具有无衍射和自我恢复的特性。提出的光束在光通信和光操纵中具有潜在的应用。
