中文摘要：

We experimentally study the generation of a partially coherent non-diffractive beam by focusing a partially coherent vortex beam with an axicon.The investigation results show that when the partially coherent vortex beam is focused by the axicon,the beam is transferred into a partially coherent higher-order non-diffractive beam.In the non-diffractive zone,the transverse intensity distribution of the partially coherent higher-order non-diffractive beam is invariant during propagation.In addition,the range of the non-diffractive zone is related to the coherence of the partially coherent vortex beam.The poorer the coherence of the partially coherent vortex beam,the shorter the range of the non-diffractive zone.

英文摘要：

We experimentally study the generation of a partially coherent non-diffractive beam by focusing a partially coherent vortex beam with an axieon. The investigation results show that when the partially coherent vortex beam is focused by the axicon, the beam is transferred into a partially coherent higher-order non-diffractive beam. In the non-diffractive zone, the transverse intensity distribution of the partially coherent higher-order non-diffractive beam is invariant during propagation. In addition, the range of the non-diffractive zone is related to the coherence of the partially coherent vortex beam. The poorer the coherence of the partially coherent vortex beam, the shorter the range of the non-diffractive zone.
