摘要: The analytical expression of off-axis hollow Gaussian-Schell model vortex beam (HGSMVB) generated by anisotropic Gaussian-Schell model source is first introduced. The evolution properties of off-axis HGSMVB propagating in turbulent atmosphere are analyzed. The results show that the off-axis HGSMVB with smaller coherence length or propagating in stronger turbulent atmosphere will evolve from dark hollow beam into Gaussian-like beam with a larger beam spot faster. The beams with different values of integer order N or the position for hollow and vortex factor R will have almost the same Gaussian-like spot distribution at the longer propagation distance.

关键词: vortex beam, off-axis beam, Gaussian-Schell model sources, laser propagation, intensity
