Propagation and coherence properties of higher order partially coherent dark hollow beams in turbulence

摘要: We formulate and evaluate in terms of graphical outputs, source receiver plane expressions, the complex degree coherence, beam size variation power bucket performance for higher order partially coherent dark hollow beams propagating turbulent atmosphere. Our formulation is able to cover square, rectangular, circular, elliptical geometries flat-topped one single expression. From outputs plane, it observed that will initially develop an outer ring around a central lobe, but eventually evolve towards Gaussian shape as propagation distance extended. It further stronger turbulence levels greater partial coherence have similar effects on profile. During propagation, modulus appears rise above values, reaching high near unity. Beam analysis shows that, among types examined, (nearly) experiences least expansion. Power indicates lowest square fully offers best capturing.
