摘　　要：为了研究大气传输效应对海上激光远场光强分布的影响,以厄米-高斯(H-G)光束的传输为例,建立了激光到达接收面的光强分布模型.根据广义惠更斯-菲涅耳原理,对TEM00模和TEM10模光束在不同大气折射率结构常数、传输距离和传输激光波长条件下的光强分布特性进行数值模拟.结果表明,在确定了大气传输效应的参量和光束参量之后,就可以判断出激光远场光强分布特性.In order to study the effects atmosphere transmission on the laser beam intensity distribution at sea, a model of laser beam intensity distribution on reaching face is established based on the example of Hermits-Gaussian （H-G）s. According to the generalized Huygens-Fresnel ＇principle, the peculiarity of laser beam intensity distribution is simulated under the different condition such as refractive index of atmospheric structure constant and transmission pace and laser wavelength. The result indicated： if the parameters of effect and beam is confirmed, the peculiarity of laser beam intensity distribution in far field can be determined.
