双曲余弦高斯光束在非 Kolmogorov湍流中的湍流距离
Turbulence distance of cosh-Gaussian beams in non-Kolmogorov turbulence
摘要
Abstract
To study the spreading of cosh-Gaussian beams propagating through non-Kolmogorov turbulence , extended Huygens-Fresnel principle was used .The expression of turbulence distance zt of partially coherent cosh-Gaussian beams propagating through turbulence was derived .The influence of turbulence parameters ( generalized exponent parameter α, inner scale l0 and outer scale L0 ) and beam parameters ( coherence parameter βand decentered parameter δ) on turbulence distance was studied theoretically .The results show that turbulence distance zt decreases firstly and then increases with the increase of α.When α=3.11, zt is minimum.And zt increases with the increase of l0 and δ, decreases with the increase of L0(just for 3.6<α<4) and β.The results will be useful for the applications of cosh-Gaussian beams propagating in non-Kolmogorov turbulence .关键词
