摘　　要：利用国内外现有资料对１０６μｍ激光的大气传输特性进行了分析归纳，得到了一些有价值的结论，并提出了一些推论。文中指出：１０６μｍ激光在大气中传输时其分子吸收效果可视为０，分子散射效果可忽略，气溶胶的吸收效果较小，故只需考虑气溶胶的散射效果；１０６μｍ激光在相同传输距离情况下在地面水平传输时衰减最大，而随着距地面高度的增加，衰减明显减少，至４０ｋｍ处衰减几乎为０。比较了１０６μｍ与１０６μｍ两种激光的传输特性。In this paper, the atmospheric transmission property of 1.06μm laser was analyzed by studying information both at home and abroad, and some valuable conclusions and inferences are presented. It is pointed out that, in the course of the atmospheric transmission of 1.06μm laser, the absorptive effect can be regarded as zero and the scattering effect of molecules can be negligible as for the gas dissolved gelatin. The scattering effect of the gas dissolved gelatin can be taken into consideration because of the scanty of absorptive effect. And with the same transmission distance, attenuation of 1.06μm laser is the largest when it is transmitted horizontally on the ground. And with the increase of the altitude of the earth′s surface the attenuation is reduced remarkably, at the point of 40 kilometer, attenuation nearly can be zero. Finally, the transmission rate of 1.06μm laser′s slope way atmospheric transmission which varies with its angle of alleviation and its range is given, the comparison of the transmission properties between 1.06μm and 10.6μm lasers is made.
