Optical twist has always been a hot spot in optics since it was discovered 1993. Twisted beams can be generated by introducing the phase into partially coherent beams, or twisting anisotropic whose spectral density and degree of coherence will spontaneously rotate during propagation. Unlike conventional twisted have unique properties used many applications, such as optical communications, laser material processing, particle manipulation.
