激光束在大气中长距离传输聚焦特性的研究
Focus Characteristics of Laser Beam for Long Distance Propagation in Atmosphere
【摘要】 研究了大气湍流与热晕对于几种不同波长激光束的长距离传输聚焦特性的影响。光束质量与光束漂移量的理论与实验值基本一致
【Abstract】 The influence of atmospheric turbulence and thermal blooming on focus characteristics of laser beam is studied for several typical lasers with different wavelength. The excursion of the laser beam axis for long distance propagation in atmosphere is obtained for several laser beam axes. The calculations coincide with the experimental result.
