【摘要】：基于臨近空間大氣基本特性,對激光與大氣相互作用進行分析和研究,采用MODTRAN軟件分析了臨近空間大氣的吸收和散射,給出了400~2000 nm波長激光的透過率曲線,從激光光斑漂移和擴展兩個方面對大氣湍流對激光傳輸?shù)挠绊戇M行數(shù)值計算,對發(fā)生熱暈效應的功率閾值進行數(shù)值估算,結論表明:與近地空間相比,臨近空間大氣對于激光傳輸影響較弱,有利于實現(xiàn)高功率激光的長距離傳輸。
[Abstract]:Based on the basic characteristics of the near space atmosphere, the interaction between the laser and the atmosphere is analyzed. The absorption and scattering of the near space atmosphere are analyzed by using MODTRAN software, and the transmittance curve of the laser at 400 ~ 2 000 nm wavelength is given. The influence of atmospheric turbulence on laser propagation is numerically calculated from two aspects of laser spot drift and expansion. The power threshold of thermal halo effect is calculated numerically. The results show that compared with near-Earth space, The near space atmosphere has a weak effect on laser transmission, which is beneficial to the long distance transmission of high power laser.
