部分相干 cosh-Gaussian光束通过大气湍流后的聚焦特性
Focusing characteristics of partially coherent cosh-Gaussian beams propagating through turbulent atmosphere
摘要
Abstract
For studying characteristics of partially coherent cosh-Gaussian beams propagating through turbulent atmosphere , analysis was carried out based on ABCD matrix and the expressions of the intensity , beam width and power in bucket were obtained to characterize the focusing characteristics of partially coherent cosh-Gaussian beams propagating through turbulent atmosphere .The results show that under different turbulence intensities , the focusing characteristics of partially coherent cosh-Gaussian beams are different from those of totally coherent cosh-Gaussian beams and that the effect of turbulence is more serious to totally coherent cosh-Gaussian beams characterized with the power in bucket and beam width .However , the influence of turbulence on the focused partially coherent cosh-Gaussian is more serious than the collimated beams .The results are useful to study the focusability of partially coherent cosh-Gaussian beams propagating through turbulent atmosphere and helpful to design applicable optical systems for incoherent combination of paraxial beams .关键词
