Abstract

We report on versatile orbital angular momentum beam generation through the association of a 61-channels coherent beam combining digital laser and a liquid-crystal q-plate. Particularly, high-order vortex beams that carry orbital angular momentum are generated with radial, azimuthal and/or circular polarization states. The q-plate is designed and manufactured to sustain high average power ensuring that the vortex spatial mode is preserved. The proposed system offers an extra degree of freedom for various applications requesting beam shaping with specific polarization state.

利用相干光束结合数字激光器和液晶 Q 板控制轨道角动量光束的产生

我们报告了通过结合数字激光器和液晶 q 板的 61 信道相干光束产生的多功能轨道角动量光束。特别是，它能以径向、方位和/或圆偏振态产生携带轨道角动量的高阶涡旋光束。q 型板的设计和制造可维持较高的平均功率，确保涡旋空间模式得以保留。所提出的系统为要求用特定偏振态进行光束整形的各种应用提供了额外的自由度。
