摘　　要：考虑到8～14μm长波红外激光在大气中传输特性优于常用的近红外激光,长波红外无线激光通信技术成为研究热点。比较了长波红外激光与近红外激光在大气中的传输性能,介绍国内外长波红外无线激光通信技术研究情况,并对系统主要关键组件进行了说明。It is known propagation properties of 8～14μm long-wave infrared（LWIR） laser are better than commonly used near-infrared laser in the atmosphere,LWIR free-space laser communications technology become the research focus.This paper should characterize with performance to adverse meteorological conditions when compared with the systems operating in the near IR.The international and domestic situation about LWIR free-space laser communications technology is introduced,and then key technologies of the system are described.
