数值研究了大气湍流对不同类型涡旋光束（包括拉盖尔-高斯（LG）光束和贝塞尔光束）轨道角动量谱的影响。我们制作了不同折射率结构常数的大气湍流全息图。分析了畸变的单模或复用LG光束和贝塞尔光束的OAM谱。与两种涡旋光束的OAM谱相比，贝塞尔光束的光谱色散更大。结果表明，贝塞尔光束比LG光束更容易受到湍流大气的影响。(C)2016中国激光出版社
We investigate the atmospheric turbulence effects on orbital angular momentum (OAM) spectra of different kinds of vortex beams, including Laguerre-Gaussian (LG) beams and Bessel beams, numerically. We generate the holograms of atmospheric turbulence with different structure constants of the refractive index. The OAM spectra of distorted single-mode or multiplexed LG beams and Bessel beams are analyzed. Compared with the OAM spectra of the two kinds of vortex beams, the spectrum of the Bessel beams is more dispersive. The results illustrate that Bessel beams suffer more from turbulent atmosphere than LG beams. (C) 2016 Chinese Laser Press
