摘　　要：在舰载激光通信系统中,激光远场光强分布对系统通信质量的提高具有重要影响。利用所建立的激光远场光强分布模型和1.06μm激光大气传输特性,研究了大气能见度对激光远场光强分布的影响。结果表明:在不考虑大气湍流影响的条件下,能见度越高,光强衰减越小;在只考虑大气湍流影响的条件下,传输激光的波长,大气折射率结构常数,对激光远场光强分布具有重要影响。In the system of ship-borne laser communication,the laser has an important influence on improving communication quality. Using the model of laser beam intensity distribution and the 1.06 μm laser transmission characteristics in the atmosphere, has studied the influence degree of the atmospheric visibility on the beam intensity distribution in far-field. The result indicated：Without considering the influence of atmospheric turbulence, the visibility is higher, the beam intensity attenuation is smaller;Under the condition that only considered the atmospheric turbulence influence ,wave length of transmission laser and refractive index of atmospheric structure constant have an important influence on beam intensity distribution.
