提出了轴棱锥聚焦贝塞尔-谢尔模型光束产生空心光束的方法。应用交叉谱密度函数模拟了贝塞尔-谢尔模型光束通过轴棱锥后的光强分布。结果表明，空心光束的尺寸随着传播距离的增加逐渐增大。使用Tracepro软件模拟验证了该空心光束的自重建特性。设计相关实验进行验证，且理论分析、数值模拟与实验结果相吻合。此研究结果对于光镊等的实际应用具有重要的参考价值。

A new method which can generate hollow beams by focusing J0-correlated Schell-model beams with an axicon is proposed. The light intensity distribution of the J0-correlated Schell-model beams after the axicon is simulated with the cross-spectral density function. The results show that the sizes of the hollow beams increase with the increasing propagation distance. The self-reconstruction property of the hollow beam is investigated by the Tracepro software. The correlation experiment is carried out. The results of the experiments are in agreement with those the theoretical analysis and the numerical simulation. This study will be a reference for applications of optical tweezers.
